action-setup-venv

Sets up python and a virtual environment with caching.

The main benefit of this action over using setup-python is that it caches the entire venv directory and will skip the pip install ... entirely when the cache is available.

Usage

uv:

    - uses: astral-sh/setup-uv@884ad927a57e558e7a70b92f2bccf9198a4be546 # v6
      with:
        version: "0.8.2"
        # we just cache the venv-dir directly in action-setup-venv
        enable-cache: false

    - uses: getsentry/action-setup-venv@v3.1.0
      with:
        cache-dependency-path: uv.lock
        install-cmd: uv sync --frozen --active

pip:

    - uses: getsentry/action-setup-venv@v3.1.0
      id: venv
      with:
        # starting from action-setup-venv@v3.0.0, if python-version isn't specified,
        # we default to using the version in .python-version file.
        python-version: 3.11.6
