Python version errors

Online experiments

I have an old PsychoPy script from 2020. My mac (14.4.1) is running Python version 3.11.7. I installed the modern version of PsychoPy. When I try to sync to Pavlovia, I get the below errors. Seems like it might be something to do with me having a newer version of Python when you recommend Python 3.10, but I don’t think installing an older version of python is so simple?? Any thoughts?

Traceback (most recent call last):

Hi,

PsychoPy comes with its own Python installation and it is therefore not affected by the Python version you have installed in your PC - indeed you can see in the error that the Python install it refers to resides within PsychoPy
File “/Applications/PsychoPy.app/Contents/Resources/lib/python3.10/psychopy/projects/pavlovia.py”

I do not have an answer to your question just wanted to clear this up. Perhaps move your .psyexp and any files (images, xlsx etc but not anything generated by syncing to Pavlovia) to a new folder and trying creating a new Palvovia project?

Godd luck!
