Important! @jon wrote a reply further down and suggested what is probably a much easier solution. (not marked as solution yet since there’s only one who has confirmed that it works for them) I started this to ask for help, but then I found out more myself, so now I’m mostly putting this here to hel…

Hi there, I just wanted to thank you for your thorough documentation of this problem and the steps that you have taken. This will be useful both for the developers and users as we move forward thinking about cross platform installation. Sorry that you had a difficult time installing, but thank you …

I, too, would like to thank you deeply for your explanation and description. Your problems are exactly the ones I ran into and I agree that more linux support would be very much appreciated. Your suggestions were extremely helpful. I love PsychoPy once it’s working, but getting it installed has bec…

After installing PsychoPy from scratch I also had the PTB priority error on openSUSE Leap 15.2.

Yippie, thanks a lot Jon! This manual helped me installing Psychopy on very recent Debian Bullsyeye. libwxgtk-webview3.0-gtk3-0v5:amd64 is available as deb. manually had to install: pip install pyosf Psychtoolbox is now version 3.0.17.8, this installs without error (3.0.16 gave error). Only is…

Ran all of these commands suggested on Ubuntu 20.04.4 LTS and psychopy crashes immediately upon running it, without any error message. I definitely recommend that the official page removes the claim that it supports linux. I deleted my windows dual-boot in order to set up ubuntu, based off of the c…
