Setup issue running with new versions of pip

[albertwilcox]

Hi,

I had an issue installing the third_party/gym-0.21.0 package when running with pip==24, leading to the following error:

  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error
  
  × python setup.py egg_info did not run successfully.
  │ exit code: 1
  ╰─> [1 lines of output]
      error in gym setup command: 'extras_require' must be a dictionary whose values are strings or lists of strings containing valid project/version requirement specifiers.
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

To solve this issue I had to run pip install pip==21 in addition to the setuptools downgrade already provided. It could be helpful to add this to the setup instructions for people who have this issue in the future.

Hi, thank you for the suggestion! I have updated the ERROR_CATCH.md to include this issue.
