Not really an option on a Mac. Docker is so incredibly slow not only because of the virtualisation layer, but because of file system performance (Python hits a lot of files on startup). It’s also not that complex at the end of the day. You have two things involved in managing python versions: the executable you’re running, and the PYTHONPATH. I actually don’t understand why people find that so complex. A virtual environment is: an alias to a python executable; a folder called ‘site-packages’ which is then added to the PYTHONPATH; and a script to set you PATH and PYTHONPATH.
