Proposed fix: [pip / Ubuntu 24.04 runner] 'error: externally-managed-environment' when pip installing into system Python on GitHub Actions ubuntu-latest
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
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
