what does it mean “the standalone version of PsychoPy”? I insalled it on the 11th of October (2 days ago) via the command “pip install psychopy”, so it is the last version 3.2.3.
The version of pyglet is 1.4.5. So, should I just downgrade pyglet to 1.3.2 to solve the issue?
You can download PsychoPy as a standalone double-clickable application on Mac and Windows, which bundles all of the dependencies, largely avoiding issues like this.
I don’t know, I’m just going off that thread above. This can unfortunately be the kind of troubleshooting that is required if you are managing dependencies yourself rather than using the standalone installer.
