psychopy-env.yml file downloadable from the installation page is out of date. It is set to use Python 3.6 and installs psychopy version: 2021.2.3.
>psychopy --version PsychoPy3, version 2021.2.3 (c)Jonathan Peirce 2018, GNU GPL license >
I’m new so I don’t know the best place to report this or if just changing the python dependency will install a newer version. But as the same page says:
This method should work on a range of versions of Python but we strongly recommend you use Python 3.8. Older Python versions are no longer being tested and may not work correctly…
So this seems to be a problem.
