PC System version: Win 10
Psychopy version: Psychopy3.1.0 or (Psychopy3.0.6, Psychopy3.1.2)

Hello everyone,

Yesterday, I updated my psychopy to Psychopy3.1.2. Today, I found I cannot open the bulider interface. In the Shell, I get this error:
subprocess.CalledProcessError: Command ‘[‘git’, ‘tag’]’ returned non-zero exit status 128.
Then I have tried reinstalling the last version 3.0.6, restalling Python, however, the problem persists.

Could anyone give some suggestions how to deal with this problem?
Thank you in advance!

Hi @Westwood, I can recreate this error if I have an empty versions folder in my AppData path. If there is no git repo in that folder, the call to git tag will fail. It perhaps got emptied when you uninstalled/upgraded PsychoPy. Go to C:\Users\USERNAME\AppData\Roaming\psychopy3\ and delete the versions folder (it should be empty, but delete anyway if it is not). This will be recreated the next time you want to set the PsychoPy version in experiment settings. The AppData folder (as well as .git folders) are hidden, so if you cannot find the AppData folder, you need to make sure you have your folder settings in Windows Explorer set to view hidden files and folders (see Microsoft docs).

It works！Thank you so much!:smiley:
