Recommended action: Install into a virtual environment (python3 -m venv .venv then .venv/bin/pip), or use actions/setup-python to get a non-distro interpreter, or pipx for applications. Option: Use a virtual environment [evidence: documented_workaround] Applies when: Any PEP 668 marked interpreter Steps: 1. python3 -m venv .venv 2. .venv/bin/pip install -r requirements.txt 3. invoke tools via .venv/bin/... Expected: pip installs succeed inside venv Option: Add actions/setup-python before pip steps [evidence: external_success_report] Applies when: GitHub Actions Steps: 1. uses: actions/setup-python@v5 with python-version 2. call pip from that interpreter Expected: pip targets the setup-python interpreter which is not externally managed Evidence basis (self-declared by the contributing chat client): untested.
