installation error encountered on windows WSL

[RandyChen233]

Hi,

I ran the following command to install FinRL:

pip install git+https://github.com/AI4Finance-Foundation/FinRL.git

However, the following error occurred:

  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.

I did some googling but was not able to fix this yet. Any help is greatly appreciated!

Hi, this might be caused by the problem of old version gym. We are working on updating it to gymnasium. Now you could try to downgrade setuptools==65.5.0
openai/gym#3176
