Heya everyone,

I’m very new to PsychoPy and encountered my first problem when opening or creating new files. When opening any file or creating a new project an unhandled internal error pops up. The following details are for a new project:

> Traceback (most recent call last):  
> File «/Applications/PsychoPy.app/Contents/Resources/lib/python3.10/psychopy/app/coder/coder.py», line 2193, in fileNew  
> File «/Applications/PsychoPy.app/Contents/Resources/lib/python3.10/psychopy/app/coder/coder.py», line 2350, in setCurrentDoc  
> File «/Applications/PsychoPy.app/Contents/Resources/lib/python3.10/psychopy/projects/pavlovia.py», line 1460, in getProject  
> psychopy.exceptions.DependencyError: gitpython and a git installation required for getProject()

And these are the details for opening a project someone had sent me:

> Traceback (most recent call last):

At first PsychoPy appears to be working when I simply click “Ok” and I can use the builder fine, but once I run experiments it goes wrong. Some things work sometimes, but for example text items don’t show up and I regularly need to close the experiment window with Cmd+Opt+Esc.  
System information down below. I tried reinstalling it, but that hasn’t changed things. Any suggestions are appreciated!

Thanks and best,  
Lukas

Hi Becca, thank you for your reply. I’ve installed it and it appears to be working fine now!
