Difference between env.pythonLocation on macOS in Python 3.11+

Description:

I'm encountering a strange issue related to caching the Python installation. I'm using actions/setup-python@v5.0.0 to install Python, then actions/cache@v4.0.0 to cache the env.pythonLocation directory, similar to this blog.

This works fantastically, except on macOS in Python 3.11 and 3.12, and I have no idea why. For some reason, the cache is empty, but only for those specific versions. Did anything change in the installation layout or env.pythonLocation variable that could explain this?

Action version:

5.0.0

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:

Python 3.11, 3.12

Repro steps:

The full workflow can be seen here.

Expected behavior:

I would expect this to work for all platforms/Python versions and cache the installed Python packages.

Actual behavior:

The cache is empty. See https://github.com/actions/cache/issues/1176 for the cross-referenced bug report.

从所引用的工作流 .github/workflows/tests.yaml 开始，比较 macOS 上 Python 3.11 和 3.12 的 env.pythonLocation 及缓存内容。结合本报告阅读其中交叉引用的 actions/cache issue 1176；完成的标准是解释清楚特定于平台/版本的行为，并且受影响的缓存行为已有经过验证的解决方案。
