Error with `conda env create -f environment_win.yml`

I am trying to install the packages through environment_win.yml and I am getting the following error:

  Using cached gym-0.21.0.tar.gz (1.5 MB)
  Preparing metadata (setup.py): started
  Preparing metadata (setup.py): finished with status 'error'

Pip subprocess error:

  × python setup.py egg_info did not run successfully.

      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.

  note: This error originates from a subprocess, and is likely not a problem with pip.

CondaEnvException: Pip failed

It seems that there is an issue with the gym package as can be seen here: https://github.com/openai/gym/issues/3176.

Hi,

You can try removing the following packages in the .yml file:

• atari-py
• gym
