A simple, correct Python build frontend.
See the [documentation](https://build.pypa.io) for more information.
### Installation
`build` can be installed via `pip` or an equivalent via:
```console
$ pip install build
```
### Usage
```console
$ python -m build
```
This will build the package in an isolated environment, generating a
source-distribution and wheel in the directory `dist/`. See the
[documentation](https://build.pypa.io) for full information. Build is also
available via the command line as `pyproject-build` once installed.
### Common arguments
- `--sdist` (`-s`): Produce just an SDist
- `--wheel` (`-w`): Produce just a wheel
- `-C<option>=<value>`: A Config-setting, the PEP 517 way of passing options to a backend. Can be passed multiple times. Matching options will make a list. Note that setuptools has very limited support.
- `--config-json=<value>`: An alternative way to pass in complex config settings as JSON strings. Can't be used with `-C`.
- `--installer`: Pick an installer for the isolated build (`pip` or `uv`).
- `--no-isolation` (`-n`): Disable build isolation.
- `--skip-dependency-check` (`-x`): Disable dependency checking when not isolated; this should be done if some requirements or version ranges are not required for non-isolated builds.
- `--outdir` (`-o`): The output directory (defaults to `dist`)
Some common combinations of arguments:
- `--sdist --wheel` (`-sw`): Produce and SDist and a wheel, both from the source distribution. The default (if no flag is passed) is to build an SDist and then build a wheel _from_ the SDist.
- `-nx`: Disable build isolation and dependency checking. Identical to pip and uv's `--no-build-isolation` flag.
### Integration with other tools
#### pipx
If you use [pipx][], such as in GitHub Actions, the following command will download
and run build in one step:
```console
$ pipx run build
```
#### uv
If you want to use [uv][] to speed up the virtual environment creation, you can
use `--installer=uv`. You can get a Python wheel for `uv` with the `[uv]`
extra. For example, using pipx like above:
```console
$ pipx run 'build[uv]' --installer uv
```
If you already have uv, you don't need the extra. For example:
```console
$ uvx --from build pyproject-build --installer uv
```
#### cibuildwheel
If you are using [cibuildwheel][], build is integrated and the default builder in 3.0+. If you want to use `uv` as the installer, you can use:
```toml
[tool.cibuildwheel]
build-frontend = "build[uv]"
```
(Be sure to pre-install uv before running cibuildwheel for this one!)
#### Conda-forge
On conda-forge, this package is called [python-build][].
### Code of Conduct
Everyone interacting in the build's codebase, issue trackers, chat rooms, and mailing lists is expected to follow
