Unhandled dependency error when opening existing project (git and gitpython)

[Henning_Holle]

Hi,

I keep on getting an unhandled internal error when trying to open an existing project, related to git and gitpython

This is from a pip install of psychopy created using Python 3.8.8rc1

Psychopy version 2024.2.4
I have also tried downgrading to 2024.2.1 or 2024.1.4 as suggested here but I always get the same error

Error message is below

Traceback (most recent call last):

I would be grateful for any advice on this

I have also tried using python 3.10, but that also did not make a difference

PsychoPy 2024.2.5 has just been released so you could try that.

Try uninstalling the previous version first.

Release 2024.2.5 · psychopy/psychopy

You should probably also clear your users.json file.

Psychopy encountered an internal problem with Pavlovia

Thank you so much for your advice! Unfortunetly, I couldn’t find a folder called .psychopy3/ on my computer. However, it seems like we can find hidden files here! Finder > Go > press option or alt key (to show Library) > Library > Preferences and I deleted a file called org.opensciencetools.psychopy Then, somehow it started working! Also on the PsychoPy Builder, instead of logging in from the Pavlovia.org button at the top of the screen, it works better if we log-in from the Builder menu!! …

Hi, I have done 2 things now,

1)
downloaded 2024.2.5, installed with pip from source code available here Release 2024.2.5 · psychopy/psychopy · GitHub

This gives me still the same error message when trying to open an existing project

Traceback (most recent call last):
File “C:\python_3_10\lib\site-packages\psychopy\app\builder\builder.py”, line 780, in fileOpen
self.project = pavlovia.getProject(filename)
File “C:\python_3_10\lib\site-packages\psychopy\projects\pavlovia.py”, line 1467, in getProject
raise exceptions.DependencyError(
psychopy.exceptions.DependencyError: gitpython and a git installation required for getProject()

2
Downloaded standalone version of 2024.2.5

Here the error message does not appear

However, I would really like to be able to use pip install so that I can quickly change versions to deal with legacy experiments. Why does the check for an exisitng git installation fail in the pip install, but not in the standalone version?

You can have multiple versions of PsychoPy installed on your computer.

just to add in case someone else has a similar problem. I was able to make option 1 (pip install psychopy) work by first installing git, available here
