stucking when running pip install gym[accept-rom-license]==0.21.0

[maguro27]

Hi.
Thank you for your great work!
Unfortunately, the pip install gym[accept-rom-license]==0.21.0 script stucks after getting the message Building wheel for AutoROM.accept-rom-license (pyproject.toml) ... -.

How can I solve it?
Thanks.

Hey, thanks for the kind words! The package is installed without any issues on our end. What is your OS and its version? Which pip version are you using, in a virtual environment?

Thank you for getting back to me.
My environment is as follows,

OS: CentOS 7.5 and Red Hat Enterprise Linux 8.2
virtual env: anaconda 4.10.3
python: 3.8
pip: 22.3.1

Hey, we cannot reproduce your exact setup but it seems reasonable. However, your issue does not lie within our codebase and I would recommend that you take a look at potential problems encountered when installing gym.
