How to cache dependencies installed via setup.py

[steveoh]

cache: pip looks for a requirements.txt file. Is it possible to cache from pip when installing a module from a setup.py?

Hello @steveoh. Thank you for your report. If you want to use cache for pip, but you do not have requirements.txt you can use cache-dependency-path to override file is used for generating hash key. You can try to use this snippet.

    - name: Set up Python
      uses: actions/setup-python@v2
      with:
        python-version: '3.9'
        cache: pip
        cache-dependency-path: setup.py # or **/setup.py

Hello @steveoh. Does it work for you ?

I'm sure it will if the file is used for cache key generating.
