I have tried to install PsychoPy via the yaml file with Anaconda on macOS, following the instructions on the PsychoPy Website. I get the following error related to pip (after a whole stack trace of stuff).
"ModuleNotFoundError: No module named ‘dataclasses’
CondaEnvException: Pip failed"
I am using the latest macOS version, on an Intel Mac, with the latest Anaconda. I tried installation via the terminal via Visual Studio Code (latest version).
I reverted back to manually creating an environment, installing pip, then installing PsychoPy. This seems to have worked. I have run a few demos and then work fine. Not a encyclopaedic testing though.
I assume the yaml file route should have worked? Was I doing something wrong?
Edit: The manual route was all via the terminal in visual studio. So, I do not think it is a visual studio or anaconda issue per se.
