After having a few issues with installing PsychoPy3 on Linux (Linux Mint 19.1), below, I listed the necessary steps to get it running. Maybe, some of the issues can be resolved with updates or by including them in the online instructions (Thanks Claire, for the final ffmpeg hint). Step 1: (not docu…

The second to last problem ( No module named ‘wx.html2’ ) is solved by installing the ‘webview’ part of wx sudo apt-get install python3-wxgtk-webview4.0 Thus wx.html2 works. However, the last problem remains: crash after a few seconds/clicks. (I updated the respective part in the initial post.) …

Hello, I was having the same kind of trouble installing Psychopy 3 on Ubuntu 18.10. What I did was to make sure that the default python was indeed python 3 (running sudo ln -sfn /usr/bin/python3 /usr/bin/python). Then I followed more or less the same steps as you did and ended up with the same pro…

I followed the steps (on Ubuntu 18.04), but at the end when I type in psychopyApp.py, the command line returns: command not found…Anyone know why?

Were you ever able to resolve this? I got the same error after installing it :frowning:

Sorry that this hasn’t been easier. I’m afraid the core team developing PsychoPy is very small and busy! That said, I just tried to install on a VM running a clean install of Ubuntu 20.04 and this appears to work: sudo apt-get install psychopy # fetches outdated version from debian sudo apt-get …

Hi Jon, I’m trying to use the DotStim, and when I try this installation followed by from psychopy.visual import DotStim, I receive a ModuleNotFoundError: No module named 'wx' error.
