============
Installation
============

``build`` can be installed via `pip`_ or an equivalent:

.. code-block:: sh

   $ pip install build

You can also check out the latest `git tag`_, download a tarball_ from GitHub, or
manually fetch the artifacts from the `project page`_ on PyPI. The git tags are
recommended for redistribution and are PGP-signed with one of the following keys:

.. tip::
   If you prefer, or are already using virtualenv_ in your workflow, you can
   install ``build`` with the optional ``virtualenv`` dependency:

   .. code-block:: sh

      $ pip install 'build[virtualenv]'

   this way, ``build`` will use virtualenv_ for isolation, instead of venv_.
   This can be particularly useful, for example, when using automation tools
   that rely on virtualenv_, such as tox_, or when your operating system's
   Python package does not include venv_ in the standard installation (such as
   some versions of Ubuntu).

Bootstrapping
=============

This package can build itself only with the ``tomli`` (can be omitted in Python 3.11+)
and ``pyproject-hooks`` dependencies.
The ``--skip-dependency-check`` flag should be used in this case.

Compatibility
=============

``build`` is verified to be compatible with the following Python
versions:

- 3.8
- 3.9
- 3.10
- 3.11
- 3.12
- PyPy3
