Permission denied when creating symlinks on macOS self-hosted runners

Description:

Problem

setup-python fails on self-hosted macOS EC2 runners with:

Error: ln: python314: Permission denied

The setup.sh installer script uses sudo to install the Python framework into /Library/Frameworks/ (line 50), but the subsequent symlink creation inside that root-owned directory runs without sudo, causing a permission error on runners where the CI user is not an admin.

Action version:
v6

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:

Any

Repro steps:
Make a deployment on a MacOS instance where the runner is running as a standard user with sudo permission.

Expected behavior:
The installation process creates symbolic links without failures.

Actual behavior:

Fix:
Can be addressed by this PR: https://github.com/actions/python-versions/pull/384

Examinez setup.sh autour de la ligne 50 ainsi que la pull request référencée dans actions/python-versions#384 afin de comprendre les étapes d’installation et de création des symlinks. Reproduisez l’installation de setup-python v6 sur un self-hosted runner macOS avec un utilisateur standard, puis confirmez que la création des liens symboliques s’effectue sans erreur de permission.
