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

pip install setuptools == 66 or modify the setup.py file to fix the issue

I'm getting the same error, it's not a setuptools version problem, it's a configuration error. Look carefully, opencv-python>=3. There is no number after 3. just change it to 3.0 or 3

I'm getting the same error, it's not a setuptools version problem, it's a configuration error. Look carefully, opencv-python>=3. There is no number after 3. just change it to 3.0 or 3

Where can I find this file and modify it?

[heiheiheibj]

I couldn't find the location of the configuration file, so i used a very inelegant way to modify the code and solved this problem. [doge] Modify /usr/local/python3.7/lib/python3.7/site-packages/wheel/vendored/packaging/requirements.py

` def init(self, requirement_string: str) -> None:

    try:

        if requirement_string.find('opencv-python>=3.')>=0:

            requirement_string += "0"    # opencv-python>=3.0

        parsed = parse_requirement(requirement_string)

`

[HelloCentaurus]

I couldn't find the location of the configuration file, so I did a very dumb solution. Modify /usr/local/python3.7/lib/python3.7/site-packages/wheel/vendored/packaging/requirements.py

` def init(self, requirement_string: str) -> None:

    try:

        if requirement_string.find('opencv-python>=3.')>=0:

            requirement_string += "0"    # opencv-python>=3.0

        parsed = parse_requirement(requirement_string)

`

Anyway, this method helped me solve the problem. Thank you very much!

Alternatively,

pip install git+https://github.com/openai/gym.git@9180d12e1b66e7e2a1a622614f787a6ec147ac40

installs gym==0.21 with the typo opencv-python>=3. fixed.

[saulfield]

This appears to be because of a change with wheel. Using wheel==0.38.4 worked for me.

[pseudo-rnd-thoughts]

In my case I just had to replace the gym== version being installed to gym, and the most recent version works, I guess.

Be aware that there are major api changes with the latest version compared to v0.21

FYI, on Windows, the file to modify manually is: C:\Users \ 'username'\AppData\Local\Programs\Python\Python'version'\Lib\site-packages\gym-0.21.0-py3.11.egg-info\requires.txt

[destroy314]

pip install "pip<24.1" works for me
