## Setting options
|
||
|
||
cibuildwheel can either be configured using environment variables, or from
|
||
config file such as `pyproject.toml`.
|
||
|
||
### Environment variables {: #environment-variables}
|
||
|
||
Environment variables can be set in your CI config. For example, to configure
|
||
cibuildwheel to run tests, add the following YAML to your CI config file:
|
||
|
||
!!! tab "GitHub Actions"
|
||
|
||
> .github/workflows/*.yml ([docs](https://help.github.com/en/actions/configuring-and-managing-workflows/using-environment-variables)) (can be global, in job, or in step)
|
||
|
||
```yaml
|
||
env:
|
||
CIBW_TEST_REQUIRES: pytest
|
||
CIBW_TEST_COMMAND: "pytest {project}/tests"
|
||
```
|
||
|
||
!!! tab "Azure Pipelines"
|
||
|
||
> azure-pipelines.yml ([docs](https://docs.microsoft.com/en-us/azure/devops/pipelines/process/variables))
|
||
|
||
```yaml
|
||
variables:
|
||
CIBW_TEST_REQUIRES: pytest
|
||
CIBW_TEST_COMMAND: "pytest {project}/tests"
|
||
```
|
||
|
||
!!! tab "Travis CI"
|
||
|
||
> .travis.yml ([docs](https://docs.travis-ci.com/user/environment-variables/))
|
||
|
||
```yaml
|
||
env:
|
||
global:
|
||
- CIBW_TEST_REQUIRES=pytest
|
||
- CIBW_TEST_COMMAND="pytest {project}/tests"
|
||
```
|
||
|
||
!!! tab "AppVeyor"
|
||
|
||
> appveyor.yml ([docs](https://www.appveyor.com/docs/build-configuration/#environment-variables))
|
||
|
||
```yaml
|
||
environment:
|
||
global:
|
||
CIBW_TEST_REQUIRES: pytest
|
||
CIBW_TEST_COMMAND: "pytest {project}\\tests"
|
||
```
|
||
|
||
!!! tab "CircleCI"
|
||
|
||
> .circleci/config.yml ([docs](https://circleci.com/docs/2.0/configuration-reference/#environment))
|
||
|
||
```yaml
|
||
jobs:
|
||
job_name:
|
||
environment:
|
||
CIBW_TEST_REQUIRES: pytest
|
||
CIBW_TEST_COMMAND: "pytest {project}/tests"
|
||
```
|
||
|
||
!!! tab "Gitlab CI"
|
||
|
||
> .gitlab-ci.yml ([docs](https://docs.gitlab.com/ee/ci/variables/README.html#create-a-custom-variable-in-gitlab-ciyml))
|
||
|
||
```yaml
|
||
linux:
|
||
variables:
|
||
CIBW_TEST_REQUIRES: pytest
|
||
CIBW_TEST_COMMAND: "pytest {project}/tests"
|
||
```
|
||
|
||
### Configuration file {: #configuration-file}
|
||
|
||
You can configure cibuildwheel with a config file, such as `pyproject.toml`.
|
||
Options have the same names as the environment variable overrides, but are
|
||
placed in `[tool.cibuildwheel]` and are lower case, with dashes, following
|
||
common [TOML][] practice. Anything placed in subsections `linux`, `windows`,
|
||
or `macos` will only affect those platforms. Lists can be used instead of
|
||
strings for items that are natually a list. Multiline strings also work just
|
||
like in in the environment variables. Environment variables will take
|
||
precedence if defined.
|
||
|
||
The example above using environment variables could have been written like this:
|
||
|
||
```toml
|
||
[tool.cibuildwheel]
|
||
test-requires = "pytest"
|
||
test-command = "pytest {project}/tests"
|
||
```
|
||
|
||
The complete set of defaults for the current version of cibuildwheel are shown below:
|
||
|
||
```toml
|
||
{% include "../cibuildwheel/resources/defaults.toml" %}
|
||
```
|
||
|
||
|
||
!!! tip
|
||
Static configuration works across all CI systems, and can be used locally if
|
||
you run `cibuildwheel --plat linux`. This is preferred, but environment
|
||
variables are better if you need to change per-matrix element
|
||
(`CIBW_BUILD` is often in this category, for example), or if you cannot or do
|
||
not want to change a `pyproject.toml` file. You can specify a different file to
|
||
use with `--config-file` on the command line, as well.
|
||
|
||
## Options summary
|
||
|
||
<div class="options-toc"></div>
|
||
|
||
## Build selection
|
||
|
||
### `CIBW_PLATFORM` {: #platform}
|
||
|
||
> Override the auto-detected target platform
|
||
|
||
Options: `auto` `linux` `macos` `windows`
|
||
|
||
Default: `auto`
|
||
|
||
`auto` will auto-detect platform using environment variables, such as `TRAVIS_OS_NAME`/`APPVEYOR`/`CIRCLECI`.
|
||
|
||
- For `linux`, you need Docker running, on macOS or Linux.
|
||
- For `macos`, you need a Mac machine. Note that cibuildwheel is going to install MacPython on your system, so you probably don't want to run this on your development machine.
|
||
- For `windows`, you need to run in Windows. cibuildwheel will install required versions of Python to `C:\cibw\python` using NuGet.
|
||
|
||
This option can also be set using the [command-line option](#command-line) `--platform`. This option is not available in the `pyproject.toml` config.
|
||
|
||
!!! tip
|
||
If you have Docker installed, you can locally debug your cibuildwheel Linux config, instead of pushing to CI to test every change. For example:
|
||
|
||
```bash
|
||
export CIBW_BUILD='cp37-*'
|
||
export CIBW_TEST_COMMAND='pytest {package}/tests'
|
||
cibuildwheel --platform linux .
|
||
```
|
||
|
||
|
||
### `CIBW_BUILD`, `CIBW_SKIP` {: #build-skip}
|
||
|
||
> Choose the Python versions to build
|
||
|
||
List of builds to build and skip. Each build has an identifier like `cp38-manylinux_x86_64` or `cp37-macosx_x86_64` - you can list specific ones to build and cibuildwheel will only build those, and/or list ones to skip and cibuildwheel won't try to build them.
|
||
|
||
When both options are specified, both conditions are applied and only builds with a tag that matches `CIBW_BUILD` and does not match `CIBW_SKIP` will be built.
|
||
|
||
When setting the options, you can use shell-style globbing syntax, as per [fnmatch](https://docs.python.org/3/library/fnmatch.html) with the addition of curly bracket syntax `{option1,option2}`, provided by [bracex](https://pypi.org/project/bracex/). All the build identifiers supported by cibuildwheel are shown below:
|
||
|
||
<div class="build-id-table-marker"></div>
|
||
|
||
| | macOS | Windows | Manylinux Intel | Manylinux Other |
|
||
|--------------|---------------------------------------------------------------------|-------------------------------|-----------------------------------------------|----------------------------------------------------------------------------|
|
||
| Python 3.6 | cp36-macosx_x86_64 | cp36-win_amd64<br/>cp36-win32 | cp36-manylinux_x86_64<br/>cp36-manylinux_i686 | cp36-manylinux_aarch64<br/>cp36-manylinux_ppc64le<br/>cp36-manylinux_s390x |
|
||
| Python 3.7 | cp37-macosx_x86_64 | cp37-win_amd64<br/>cp37-win32 | cp37-manylinux_x86_64<br/>cp37-manylinux_i686 | cp37-manylinux_aarch64<br/>cp37-manylinux_ppc64le<br/>cp37-manylinux_s390x |
|
||
| Python 3.8 | cp38-macosx_x86_64<br/>cp38-macosx_universal2<br/>cp38-macosx_arm64 | cp38-win_amd64<br/>cp38-win32 | cp38-manylinux_x86_64<br/>cp38-manylinux_i686 | cp38-manylinux_aarch64<br/>cp38-manylinux_ppc64le<br/>cp38-manylinux_s390x |
|
||
| Python 3.9 | cp39-macosx_x86_64<br/>cp39-macosx_universal2<br/>cp39-macosx_arm64 | cp39-win_amd64<br/>cp39-win32 | cp39-manylinux_x86_64<br/>cp39-manylinux_i686 | cp39-manylinux_aarch64<br/>cp39-manylinux_ppc64le<br/>cp39-manylinux_s390x |
|
||
| PyPy3.7 v7.3 | pp37-macosx_x86_64 | pp37-win_amd64 | pp37-manylinux_x86_64 | |
|
||
|
||
|
||
The list of supported and currently selected build identifiers can also be retrieved by passing the `--print-build-identifiers` flag to cibuildwheel.
|
||
The format is `python_tag-platform_tag`, with tags similar to those in [PEP 425](https://www.python.org/dev/peps/pep-0425/#details).
|
||
|
||
For CPython, the minimally supported macOS version is 10.9; for PyPy 3.7, macOS 10.13 or higher is required.
|
||
|
||
See the [cibuildwheel 1 documentation](https://cibuildwheel.readthedocs.io/en/1.x/) for past end of life versions of Python, and PyPy2.7.

```
|
||
|
||
It is generally recommended to set `CIBW_BUILD` as an environment variable, though `skip`
|
||
tends to be useful in a config file; you can statically declare that you don't
|
||
support pypy, for example.

### `CIBW_ARCHS` {: #archs}
|
||
> Change the architectures built on your machine by default.
|
||
|
||
A list of architectures to build.
|
||
|
||
On macOS, this option can be used to cross-compile between `x86_64`,
|
||
`universal2` and `arm64` for Apple Silicon support.
|
||
|
||
On Linux, this option can be used to build non-native architectures under
|
||
emulation. See [this guide](faq.md#emulation) for more information.
|
||
|
||
Options:
|
||
|
||
- Linux: `x86_64` `i686` `aarch64` `ppc64le` `s390x`
|
||
- macOS: `x86_64` `arm64` `universal2`
|
||
- Windows: `AMD64` `x86`
|
||
- `auto`: The default archs for your machine - see the table below.
|
||
- `auto64`: Just the 64-bit auto archs
|
||
- `auto32`: Just the 32-bit auto archs
|
||
- `native`: the native arch of the build machine - Matches [`platform.machine()`](https://docs.python.org/3/library/platform.html#platform.machine).
|
||
- `all` : expands to all the architectures supported on this OS. You may want
|
||
to use [CIBW_BUILD](#build-skip) with this option to target specific
|
||
architectures via build selectors.
|
||
|
||
Default: `auto`
|
||
|
||
| Runner | `native` | `auto` | `auto64` | `auto32` |
|
||
|---|---|---|---|---|
|
||
| Linux / Intel | `x86_64` | `x86_64` `i686` | `x86_64` | `i686` |
|
||
| Windows / Intel | `AMD64` | `AMD64` `x86` | `AMD64` | `x86` |
|
||
| macOS / Intel | `x86_64` | `x86_64` | `x86_64` | |
|
||
| macOS / Apple Silicon | `arm64` | `arm64` `universal2` | `arm64` `universal2`| |
|
||
|
||
If not listed above, `auto` is the same as `native`.

|
||
[binfmt]: https://hub.docker.com/r/tonistiigi/binfmt
|
||
|
||
Platform-specific environment variables are also available:<br/>
|
||
`CIBW_ARCHS_MACOS` | `CIBW_ARCHS_WINDOWS` | `CIBW_ARCHS_LINUX`
|
||
|
||
This option can also be set using the [command-line option](#command-line) `--archs`.
|
||
|
||
#### Examples
|
||
|
||
!!! tab examples "Environment variables"
|
||
|
||
```yaml
|
||
# Build `universal2` and `arm64` wheels on an Intel runner.
|
||
# Note that the `arm64` wheel and the `arm64` part of the `universal2`
|
||
# wheel cannot be tested in this configuration.
|
||
CIBW_ARCHS_MACOS: "x86_64 universal2 arm64"
|
||
|
||
# On an Linux Intel runner with qemu installed, build Intel and ARM wheels
|
||
CIBW_ARCHS_LINUX: "auto aarch64"
|
||
```
|
||
|
||
Separate multiple archs with a space.
|
||
|
||
!!! tab examples "pyproject.toml"
|
||
|
||
```toml
|
||
# Build `universal2` and `arm64` wheels on an Intel runner.
|
||
# Note that the `arm64` wheel and the `arm64` part of the `universal2`
|
||
# wheel cannot be tested in this configuration.
|
||
[tool.cibuildwheel.macos]
|
||
archs = ["x86_64", "universal2", "arm64"]
|
||
|
||
# On an Linux Intel runner with qemu installed, build Intel and ARM wheels
|
||
[tool.cibuildwheel.linux]
|
||
archs = ["auto", "aarch64"]
|
||
```
|
||
|
||
It is generally recommended to use the environment variable or
|
||
command-line option for Linux, as selecting archs often depends
|
||
on your specific runner having qemu installed.
|
||
|
||
|
||
### `CIBW_PROJECT_REQUIRES_PYTHON` {: #requires-python}
|
||
> Manually set the Python compatibility of your project
|
||
|
||
By default, cibuildwheel reads your package's Python compatibility from
|
||
`pyproject.toml` following [PEP621](https://www.python.org/dev/peps/pep-0621/)
|
||
or from `setup.cfg`; finally it will try to inspect the AST of `setup.py` for a
|
||
simple keyword assignment in a top level function call. If you need to override
|
||
this behaviour for some reason, you can use this option.
|
||
|
||
When setting this option, the syntax is the same as `project.requires-python`,
|
||
using 'version specifiers' like `>=3.6`, according to
|
||
[PEP440](https://www.python.org/dev/peps/pep-0440/#version-specifiers).
|
||
|
||
Default: reads your package's Python compatibility from `pyproject.toml`
|
||
(`project.requires-python`) or `setup.cfg` (`options.python_requires`) or
|
||
`setup.py` `setup(python_requires="...")`. If not found, cibuildwheel assumes
|
||
the package is compatible with all versions of Python that it can build.
|
||
|
||
|
||
!!! note
|
||
Rather than using this option, it's recommended you set
|
||
`project.requires-python` in `pyproject.toml` instead:
|
||
Example `pyproject.toml`:
|
||
|
||
[project]
|
||
requires-python = ">=3.6"
|
||
|
||
# Aside - in pyproject.toml you should always specify minimal build
|
||
# system options, like this:
|
||
|
||
[build-system]
|
||
requires = ["setuptools>=42", "wheel"]
|
||
build-backend = "setuptools.build_meta"
|
||
|
||
|
||
Currently, setuptools has not yet added support for reading this value from
|
||
pyproject.toml yet, and so does not copy it to Requires-Python in the wheel
|
||
metadata. This mechanism is used by pip to scan through older versions of
|
||
your package until it finds a release compatible with the current version
|
||
of Python compatible when installing, so it is an important value to set if
|
||
you plan to drop support for a version of Python in the future.
|
||
|
||
If you don't want to list this value twice, you can also use the setuptools
|
||
specific location in `setup.cfg` and cibuildwheel will detect it from
|
||
there. Example `setup.cfg`:
|
||
|
||
[options]
|
||
python_requires = ">=3.6"
|
||
|
||
|
||
This option is not available in `pyproject.toml` under
|
||
`tool.cibuildwheel.project-requires-python`, since it should be set with the
|
||
[PEP621](https://www.python.org/dev/peps/pep-0621/) location instead,
|
||
`project.requires-python`.
|
||
|
||
#### Examples
|
||
|
||
!!! tab examples "Environment variables"
|
||
|
||
```yaml
|
||
CIBW_PROJECT_REQUIRES_PYTHON: ">=3.6"
|
||
```
|
||
|
||
### `CIBW_PRERELEASE_PYTHONS` {: #prerelease-pythons}
|
||
> Enable building with pre-release versions of Python if available
|
||
|
||
During the beta period, when new versions of Python are being tested,
|
||
cibuildwheel will often gain early support for beta releases. If you would
|
||
like to test wheel building with these versions, you can enable this flag.
|
||
|
||
!!! caution
|
||
This option is provided for testing purposes only. It is not
|
||
recommended to distribute wheels built when `CIBW_PRERELEASE_PYTHONS` is
|
||
set, such as uploading to PyPI. Please _do not_ upload these wheels to
|
||
PyPI, as they are not guaranteed to work with the final Python release.
|
||
Once Python is ABI stable and enters the release candidate phase, that
|
||
version of Python will become available without this flag.
|
||
|
||
Default: Off (0) if Python is available in beta phase. No effect otherwise.
|
||
|
||
This option can also be set using the [command-line option](#command-line) `--prerelease-pythons`. This option is not available in the `pyproject.toml` config.
|
||
|
||
#### Examples
|
||
|
||
!!! tab examples "Environment variables"
|
||
|
||
```yaml
|
||
# Include latest Python beta
|
||
CIBW_PRERELEASE_PYTHONS: True
|
||
```
|
||
|
||
## Build customization
|
||
|
||
### `CIBW_BUILD_FRONTEND` {: #build-frontend}
|
||
> Set the tool to use to build, either "pip" (default for now) or "build"
|
||
|
||
Choose which build backend to use. Can either be "pip", which will run
|
||
`python -m pip wheel`, or "build", which will run `python -m build --wheel`.
|
||
|
||
!!! tip
|
||
Until v2.0.0, [pip] was the only way to build wheels, and is still the
|
||
default. However, we expect that at some point in the future, cibuildwheel
|
||
will change the default to [build], in line with the PyPA's recommendation.
|
||
If you want to try `build` before this, you can use this option.

### `CIBW_ENVIRONMENT` {: #environment}
|
||
> Set environment variables needed during the build
|
||
|
||
A list of environment variables to set during the build. Bash syntax should be used, even on Windows.
|
||
|
||
You must set this variable to pass variables to Linux builds (since they execute in a Docker container). It also works for the other platforms.
|
||
|
||
You can use `$PATH` syntax to insert other variables, or the `$(pwd)` syntax to insert the output of other shell commands.
|
||
|
||
To specify more than one environment variable, separate the assignments by spaces.
|
||
|
||
Platform-specific environment variables are also available:<br/>
|
||
`CIBW_ENVIRONMENT_MACOS` | `CIBW_ENVIRONMENT_WINDOWS` | `CIBW_ENVIRONMENT_LINUX`

|
||
BUILD_TIME = "$(date)"
|
||
SAMPLE_TEXT = "sample text"
|
||
```
|
||
|
||
In configuration mode, you can use a [TOML][] table instead of a raw string as shown above.
|
||
|
||
!!! note
|
||
cibuildwheel always defines the environment variable `CIBUILDWHEEL=1`. This can be useful for [building wheels with optional extensions](faq.md#building-packages-with-optional-c-extensions).
|
||
|
||
### `CIBW_BEFORE_ALL` {: #before-all}
|
||
> Execute a shell command on the build system before any wheels are built.
|
||
|
||
Shell command to prepare a common part of the project (e.g. build or install libraries which does not depend on the specific version of Python).
|
||
|
||
This option is very useful for the Linux build, where builds take place in isolated Docker containers managed by cibuildwheel. This command will run inside the container before the wheel builds start. Note, if you're building both `x86_64` and `i686` wheels (the default), your build uses two different Docker images. In that case, this command will execute twice - once per build container.
|
||
|
||
The placeholder `{package}` can be used here; it will be replaced by the path to the package being built by cibuildwheel.
|
||
|
||
On Windows and macOS, the version of Python available inside `CIBW_BEFORE_ALL` is whatever is available on the host machine. On Linux, a modern Python version is available on PATH.
|
||
|
||
Platform-specific environment variables also available:<br/>
|
||
`CIBW_BEFORE_ALL_MACOS` | `CIBW_BEFORE_ALL_WINDOWS` | `CIBW_BEFORE_ALL_LINUX`
|
||
|
||
#### Examples
|
||
|
||
!!! tab examples "Environment variables"
|
||
|
||
```yaml
|
||
# Build third party library
|
||
CIBW_BEFORE_ALL: make -C third_party_lib
|
||
|
||
# Install system library
|
||
CIBW_BEFORE_ALL_LINUX: yum install -y libffi-devel
|
||
|
||
# Chain multiple commands using && and > in a YAML file, like:
|
||
CIBW_BEFORE_ALL: >
|
||
yum install bzip2 -y &&
|
||
make third_party
|
||
```
|
||
|
||
For multiline commands, see the last example. The character `>` means that
|
||
whitespace is collapsed to a single line, and '&&' between each command
|
||
ensures that errors are not ignored. [Further reading on multiline YAML
|
||
here.](https://yaml-multiline.info).
|
||
|
||
!!! tab examples "pyproject.toml"
|
||
|
||
```toml
|
||
# Build third party library
|
||
[tool.cibuildwheel]
|
||
before-all = "make -C third_party_lib"
|
||
|
||
# Install system library
|
||
[tool.cibuildwheel.linux]
|
||
before-all = "yum install -y libffi-devel"
|
||
|
||
# Run multiple commands using an array
|
||
before-all = [
|
||
"yum install bzip2 -y",
|
||
"make third_party",
|
||
]
|
||
```
|
||
|
||
In configuration files, you can use a TOML array, and each line will be run sequentially - joined with `&&`.
|
||
|
||
Note that manylinux2_24 builds occur inside a Debian9 docker, where
|
||
manylinux2010 and manylinux2014 builds occur inside a CentOS one. So for
|
||
`manylinux2_24` the `CIBW_BEFORE_ALL_LINUX` command must use `apt-get -y`
|
||
instead.
|
||
|
||
### `CIBW_BEFORE_BUILD` {: #before-build}
|
||
> Execute a shell command preparing each wheel's build
|
||
|
||
A shell command to run before building the wheel. This option allows you to run a command in **each** Python environment before the `pip wheel` command. This is useful if you need to set up some dependency so it's available during the build.
|
||
|
||
If dependencies are required to build your wheel (for example if you include a header from a Python module), instead of using this command, we recommend adding requirements to a `pyproject.toml` file's `build-system.requires` array instead. This is reproducible, and users who do not get your wheels (such as Alpine or ClearLinux users) will still benefit.
|
||
|
||
The active Python binary can be accessed using `python`, and pip with `pip`; cibuildwheel makes sure the right version of Python and pip will be executed. The placeholder `{package}` can be used here; it will be replaced by the path to the package being built by cibuildwheel.
|
||
|
||
The command is run in a shell, so you can write things like `cmd1 && cmd2`.
|
||
|
||
Platform-specific environment variables are also available:<br/>
|
||
`CIBW_BEFORE_BUILD_MACOS` | `CIBW_BEFORE_BUILD_WINDOWS` | `CIBW_BEFORE_BUILD_LINUX`
|
||
|
||
#### Examples
|
||
|
||
!!! tab examples "Environment variables"
|
||
|
||
```yaml

||
# Install something required for the build (you might want to use pyproject.toml instead)

# If cibuildwheel is called with a package_dir argument, it's available as {package}
|
||
CIBW_BEFORE_BUILD: "{package}/script/prepare_for_build.sh"
|
||
```
|
||
|
||
!!! tab examples "pyproject.toml"
|
||
|
||
```toml
|
||
[tool.cibuildwheel]
|
||
|
||
# Install something required for the build
|
||
# (you might want to use build-system.requires instead)
|
||
before-build = "pip install pybind11"
|
||
|
||
# Chain commands using && or make an array.
|
||
before-build = "python scripts/install-deps.py && make clean"
|
||
before-build = [
|
||
"python scripts/install-deps.py",

# Run a script that's inside your project
|
||
before-build = "bash scripts/prepare_for_build.sh"
|
||
|
||
# If cibuildwheel is called with a package_dir argument, it's available as {package}
|
||
before-build = "{package}/script/prepare_for_build.sh"
|
||
```
|
||
|
||
In configuration mode, you can use a array, and the items will be joined with `&&`. In TOML, using a single-quote string will avoid escapes - useful for
|
||
Windows paths.
|
||
|
||
!!! note
|
||
If you need Python dependencies installed for the build, we recommend using
|
||
`pyproject.toml`'s `build-system.requires` instead. This is an example
|
||
`pyproject.toml` file:
|
||
|
||
[build-system]
|
||
requires = [
|
||
"setuptools>=42",
|
||
"wheel",
|
||
"Cython",
|
||
"numpy==1.13.3; python_version<'3.5'",
|
||
"oldest-supported-numpy; python_version>='3.5'",
|
||
]
|
||
|
||
build-backend = "setuptools.build_meta"
|
||
|
||
This [PEP 517][]/[PEP 518][] style build allows you to completely control
|
||
the build environment in cibuildwheel, [PyPA-build][], and pip, doesn't
|
||
force downstream users to install anything they don't need, and lets you do
|
||
more complex pinning (Cython, for example, requires a wheel to be built
|
||
with an equal or earlier version of NumPy; pinning in this way is the only
|
||
way to ensure your module works on all available NumPy versions).

### `CIBW_REPAIR_WHEEL_COMMAND` {: #repair-wheel-command}
|
||
> Execute a shell command to repair each (non-pure Python) built wheel
|
||
|
||
Default:
|
||
|
||
- on Linux: `'auditwheel repair -w {dest_dir} {wheel}'`
|
||
- on macOS: `'delocate-listdeps {wheel} && delocate-wheel --require-archs {delocate_archs} -w {dest_dir} {wheel}'`
|
||
- on Windows: `''`
|
||
|
||
A shell command to repair a built wheel by copying external library dependencies into the wheel tree and relinking them.
|
||
The command is run on each built wheel (except for pure Python ones) before testing it.
|
||
|
||
The following placeholders must be used inside the command and will be replaced by cibuildwheel:
|
||
|
||
- `{wheel}` for the absolute path to the built wheel
|
||
- `{dest_dir}` for the absolute path of the directory where to create the repaired wheel
|
||
- `{delocate_archs}` (macOS only) comma-separated list of architectures in the wheel.
|
||
|
||
The command is run in a shell, so you can run multiple commands like `cmd1 && cmd2`.
|
||
|
||
Platform-specific environment variables are also available:<br/>
|
||
`CIBW_REPAIR_WHEEL_COMMAND_MACOS` | `CIBW_REPAIR_WHEEL_COMMAND_WINDOWS` | `CIBW_REPAIR_WHEEL_COMMAND_LINUX`
|
||
|
||
!!! tip
|
||
cibuildwheel doesn't yet ship a default repair command for Windows.
|
||
|
||
**If that's an issue for you, check out [delvewheel]** - a new package that aims to do the same as auditwheel or delocate for Windows.
|
||
|
||
Because delvewheel is still relatively early-stage, cibuildwheel does not yet run it by default. However, we'd recommend giving it a try! See the examples below for usage.

|
||
|
||
### CIBW_MANYLINUX_*_IMAGE {: #manylinux-image}
|
||
> Specify alternative manylinux Docker images
|
||
|
||
The available options are:
|
||
|
||
- `CIBW_MANYLINUX_X86_64_IMAGE`
|
||
- `CIBW_MANYLINUX_I686_IMAGE`
|
||
- `CIBW_MANYLINUX_PYPY_X86_64_IMAGE`
|
||
- `CIBW_MANYLINUX_AARCH64_IMAGE`
|
||
- `CIBW_MANYLINUX_PPC64LE_IMAGE`
|
||
- `CIBW_MANYLINUX_S390X_IMAGE`
|
||
- `CIBW_MANYLINUX_PYPY_AARCH64_IMAGE`
|
||
- `CIBW_MANYLINUX_PYPY_I686_IMAGE`
|
||
|
||
Set an alternative Docker image to be used for building [manylinux](https://github.com/pypa/manylinux) wheels. cibuildwheel will then pull these instead of the default images, [`quay.io/pypa/manylinux2010_x86_64`](https://quay.io/pypa/manylinux2010_x86_64), [`quay.io/pypa/manylinux2010_i686`](https://quay.io/pypa/manylinux2010_i686), [`quay.io/pypa/manylinux2010_x86_64`](https://quay.io/pypa/manylinux2010_x86_64), [`quay.io/pypa/manylinux2014_aarch64`](https://quay.io/pypa/manylinux2014_aarch64), [`quay.io/pypa/manylinux2014_ppc64le`](https://quay.io/pypa/manylinux2014_ppc64le), and [`quay.io/pypa/manylinux2014_s390x`](https://quay.io/pypa/manylinux2010_s390x).
|
||
|
||
The value of this option can either be set to `manylinux1`, `manylinux2010`, `manylinux2014` or `manylinux_2_24` to use a pinned version of the [official manylinux images](https://github.com/pypa/manylinux). Alternatively, set these options to any other valid Docker image name. For PyPy, the `manylinux1` image is not available. For architectures other
|
||
than x86 (x86\_64 and i686) `manylinux2014` or `manylinux_2_24` must be used, because the first version of the manylinux specification that supports additional architectures is `manylinux2014`.
|
||
|
||
|
||
If setting a custom Docker image, you'll need to make sure it can be used in the same way as the official, default Docker images: all necessary Python and pip versions need to be present in `/opt/python/`, and the auditwheel tool needs to be present for cibuildwheel to work. Apart from that, the architecture and relevant shared system libraries need to be compatible to the relevant standard to produce valid manylinux1/manylinux2010/manylinux2014/manylinux_2_24 wheels (see [pypa/manylinux on GitHub](https://github.com/pypa/manylinux), [PEP 513](https://www.python.org/dev/peps/pep-0513/), [PEP 571](https://www.python.org/dev/peps/pep-0571/), [PEP 599](https://www.python.org/dev/peps/pep-0599/) and [PEP 600](https://www.python.org/dev/peps/pep-0600/) for more details).
|
||
|
||
Auditwheel detects the version of the manylinux standard in the Docker image through the `AUDITWHEEL_PLAT` environment variable, as cibuildwheel has no way of detecting the correct `--plat` command line argument to pass to auditwheel for a custom image. If a Docker image does not correctly set this `AUDITWHEEL_PLAT` environment variable, the `CIBW_ENVIRONMENT` option can be used to do so (e.g., `CIBW_ENVIRONMENT='AUDITWHEEL_PLAT="manylinux2010_$(uname -m)"'`).

cibuildwheel. This represents a known-good set of dependencies, and is
|
||
recommended for build repeatability.
|
||
|
||
If set to `latest`, cibuildwheel will use the latest of these packages that
|
||
are available on PyPI. This might be preferable if these packages have bug
|
||
fixes that can't wait for a new cibuildwheel release.
|
||
|
||
To control the versions of dependencies yourself, you can supply a [pip
|
||
constraints](https://pip.pypa.io/en/stable/user_guide/#constraints-files) file
|
||
here and it will be used instead.
|
||
|
||
!!! note
|
||
If you need different dependencies for each python version, provide them
|
||
in the same folder with a `-pythonXY` suffix. e.g. if your
|
||
`CIBW_DEPENDENCY_VERSIONS=./constraints.txt`, cibuildwheel will use
|
||
`./constraints-python37.txt` on Python 3.7, or fallback to
|
||
`./constraints.txt` if that's not found.
|
||
|
||
Platform-specific environment variables are also available:<br/>
|
||
`CIBW_DEPENDENCY_VERSIONS_MACOS` | `CIBW_DEPENDENCY_VERSIONS_WINDOWS`
|
||
|
||
!!! note
|
||
This option does not affect the tools used on the Linux build - those versions
|
||
are bundled with the manylinux image that cibuildwheel uses. To change
|
||
dependency versions on Linux, use the [CIBW_MANYLINUX_*](#manylinux-image)
|
||
options.
|
||
|
||
#### Examples
|
||
|
||
!!! tab examples "Environment variables"
|
||
|
||
```yaml
|
||
# Use tools versions that are bundled with cibuildwheel (this is the default)
|
||
CIBW_DEPENDENCY_VERSIONS: pinned
|
||
|
||
# Use the latest versions available on PyPI
|
||
CIBW_DEPENDENCY_VERSIONS: latest
|
||
|
||
# Use your own pip constraints file
|
||
CIBW_DEPENDENCY_VERSIONS: ./constraints.txt
|
||
```
|
||
|
||
!!! tab examples "pyproject.toml"
|
||
|
||
```toml
|
||
[tool.cibuildwheel]
|
||
# Use tools versions that are bundled with cibuildwheel (this is the default)
|
||
dependency-versions = "pinned"
|
||
|

|
||
|

```
|
||
|
||
## Testing
|
||
|
||
### `CIBW_TEST_COMMAND` {: #test-command}
|
||
> Execute a shell command to test each built wheel
|
||
|
||
Shell command to run tests after the build. The wheel will be installed
|
||
automatically and available for import from the tests. To ensure the wheel is
|
||
imported by your tests (instead of your source copy), **tests are not run from
|
||
your project directory**. Use the placeholders `{project}` and `{package}` when
|
||
specifying paths in your project. If this variable is not set, your wheel will
|
||
not be installed after building.
|
||
|
||
- `{project}` is an absolute path to the project root - the working directory
|
||
where cibuildwheel was called.
|
||
- `{package}` is the path to the package being built - the `package_dir`
|
||
argument supplied to cibuildwheel on the command line.
|
||
|
||
The command is run in a shell, so you can write things like `cmd1 && cmd2`.
|
||
|
||
Platform-specific environment variables are also available:<br/>
|
||
`CIBW_TEST_COMMAND_MACOS` | `CIBW_TEST_COMMAND_WINDOWS` | `CIBW_TEST_COMMAND_LINUX`
|
||
|
||
#### Examples
|
||
|
||
!!! tab examples "Environment variables"
|
||
|
||
```yaml
|
||
# Run the project tests against the installed wheel using `nose`
|
||
CIBW_TEST_COMMAND: nosetests {project}/tests
|
||
|
||
# Run the package tests using `pytest`
|
||
CIBW_TEST_COMMAND: pytest {package}/tests
|
||
|
||
# Trigger an install of the package, but run nothing of note
|
||
CIBW_TEST_COMMAND: "echo Wheel installed"
|
||
|
||
# Multi-line example - join with && on all platforms
|
||
CIBW_TEST_COMMAND: >
|
||
pytest {package}/tests &&
|
||
python {package}/test.py
|
||
```
|
||
|
||
!!! tab examples "pyproject.toml"
|
||
|
||
```toml
|
||
[tool.cibuildwheel]
|
||
# Run the project tests against the installed wheel using `nose`
|
||
test-command = "nosetests {project}/tests"
|
||
|
||
# Run the package tests using `pytest`
|
||
test-command = "pytest {package}/tests"
|
||
|
||
# Trigger an install of the package, but run nothing of note
|
||
test-command = "echo Wheel installed"
|
||
|
||
# Multiline example
|
||
test-command = [
|
||
"pytest {package}/tests",
|
||
"python {package}/test.py",
|
||
]
|
||
```
|
||
|
||
In configuration files, you can use an array, and the items will be joined with `&&`.
|
||
|
||
|
||
### `CIBW_BEFORE_TEST` {: #before-test}
|
||
> Execute a shell command before testing each wheel
|
||
|
||
A shell command to run in **each** test virtual environment, before your wheel is installed and tested. This is useful if you need to install a non-pip package, invoke pip with different environment variables,
|
||
or perform a multi-step pip installation (e.g. installing scikit-build or Cython before installing test package).
|
||
|
||
The active Python binary can be accessed using `python`, and pip with `pip`; cibuildwheel makes sure the right version of Python and pip will be executed. The placeholder `{package}` can be used here; it will be replaced by the path to the package being built by cibuildwheel.
|
||
|
||
The command is run in a shell, so you can write things like `cmd1 && cmd2`.
|
||
|
||
Platform-specific environment variables are also available:<br/>
|
||
`CIBW_BEFORE_TEST_MACOS` | `CIBW_BEFORE_TEST_WINDOWS` | `CIBW_BEFORE_TEST_LINUX`
|
||
|

||
### `CIBW_TEST_REQUIRES` {: #test-requires}
|
||
> Install Python dependencies before running the tests
|
||
|
||
Space-separated list of dependencies required for running the tests.
|
||
|
||
Platform-specific environment variables are also available:<br/>
|
||
`CIBW_TEST_REQUIRES_MACOS` | `CIBW_TEST_REQUIRES_WINDOWS` | `CIBW_TEST_REQUIRES_LINUX`
|

#### Examples
|
||
|
||
!!! tab examples "Environment variables"
|
||
|
||
```yaml
|
||
# Install pytest before running CIBW_TEST_COMMAND
|
||
CIBW_TEST_REQUIRES: pytest
|
||
|
||
# Install specific versions of test dependencies
|
||
CIBW_TEST_REQUIRES: nose==1.3.7 moto==0.4.31
|
||
```
|
||
|
||
!!! tab examples "pyproject.toml"
|
||
|
||
```toml

|
||
```
|
||
|
||
In configuration files, you can use an array, and the items will be joined with a space.
|
||
|
||
|
||
### `CIBW_TEST_EXTRAS` {: #test-extras}
|
||
> Install your wheel for testing using `extras_require`
|
||
|
||
List of
|
||
[extras_require](https://setuptools.readthedocs.io/en/latest/setuptools.html#declaring-extras-optional-features-with-their-own-dependencies)
|
||
options that should be included when installing the wheel prior to running the
|
||
tests. This can be used to avoid having to redefine test dependencies in
|
||
`CIBW_TEST_REQUIRES` if they are already defined in `setup.py` or
|
||
`setup.cfg`.
|
||
|
||
Platform-specific environment variables are also available:<br/>
|
||
`CIBW_TEST_EXTRAS_MACOS` | `CIBW_TEST_EXTRAS_WINDOWS` | `CIBW_TEST_EXTRAS_LINUX`
|
||
|
||
#### Examples
|
||
|
||
!!! tab examples "Environment variables"
|
||
|
||
```yaml
|
||
# Will cause the wheel to be installed with `pip install <wheel_file>[test,qt]`
|
||
CIBW_TEST_EXTRAS: "test,qt"
|
||
```
|
||
|
||
Separate multiple items with a comma.
|
||
|
||
!!! tab examples "pyproject.toml"
|
||
|

# Will cause the wheel to be installed with `pip install <wheel_file>[test,qt]`
|
||
test-extras: ["test", "qt"]
|
||
```
|
||
|
||
In configuration files, you can use an inline array, and the items will be joined with a comma.
|
||
|
||
### `CIBW_TEST_SKIP` {: #test-skip}
|
||
> Skip running tests on some builds
|
||
|
||
This will skip testing on any identifiers that match the given skip patterns (see [`CIBW_SKIP`](#build-skip)). This can be used to mask out tests for wheels that have missing dependencies upstream that are slow or hard to build, or to skip slow tests on emulated architectures.
|
||
|
||
With macOS `universal2` wheels, you can also skip the individual archs inside the wheel using an `:arch` suffix. For example, `cp39-macosx_universal2:x86_64` or `cp39-macosx_universal2:arm64`.
|
||
|
||
#### Examples
|
||
|
||
!!! tab examples "Environment variables"
|
||
|
||
```yaml
|
||
# Will avoid testing on emulated architectures
|
||
CIBW_TEST_SKIP: "*-manylinux_{aarch64,ppc64le,s390x}"
|
||
|
||
# Skip trying to test arm64 builds on Intel Macs
|
||
CIBW_TEST_SKIP: "*-macosx_arm64 *-macosx_universal2:arm64"
|
||
```
|
||
|
||

|
||
|
||
# Skip trying to test arm64 builds on Intel Macs
|
||
test-skip = "*-macosx_arm64 *-macosx_universal2:arm64"
|
||
```
|
||
|
||
## Other
|
||
|
||
### `CIBW_BUILD_VERBOSITY` {: #build-verbosity}
|
||
> Increase/decrease the output of pip wheel
|
||
|
||
An number from 1 to 3 to increase the level of verbosity (corresponding to invoking pip with `-v`, `-vv`, and `-vvv`), between -1 and -3 (`-q`, `-qq`, and `-qqq`), or just 0 (default verbosity). These flags are useful while debugging a build when the output of the actual build invoked by `pip wheel` is required.
|
||
|
||
Platform-specific environment variables are also available:<br/>
|
||
`CIBW_BUILD_VERBOSITY_MACOS` | `CIBW_BUILD_VERBOSITY_WINDOWS` | `CIBW_BUILD_VERBOSITY_LINUX`
