ModuleNotFoundError: No module named 'pyglet'

Thanks to all who have helped so far. I got pip (actually pip3) installed as well as pyglet. But when I try to run the following in PyCharm:

import pyglet

I get: ModuleNotFoundError: No module named ‘pyglet’

Suggestions? And why is this so darned difficult?

Could be that your system default pip/python is not the one that is used by pycharm.

It’s been a long time since I’ve used pycharm, but they have a doc which talks about managing python packages from within it. Have you reviewed this? Install, uninstall, and upgrade packages | PyCharm

Thank you so MUCH! That link solved my problem, and the instructions are quite clear. Anyone else following that link notice that is says you need to download PyCharm 2021.1. Thanks to all on this great list who tried to help me.
