it’s solved now, after a friend pointed me to the troubleshooting page
- run
python -c "from psychopy import prefs; print(prefs.paths['userPrefsDir'])"
to find where your psychopy directory is - look at the contents of
last_app_load.log
in that directory - in my case, it showed me the true error:
libwebkitgtk-1.0-0
was missing, so:sudo apt-get install libwebkitgtk-1.0-0
- after that it errored again because it didn’t find any sound library. I fixed that with
pip install pygame
Now it’s working as it should
