This is similar to what I do, except my "new environment" alias executes a function that takes a python version, installed/specified via pyenv. Never had a sin

This is similar to what I do, except my "new environment" alias executes a function that takes a python version, installed/specified via pyenv. Never had a single problem, venv + pyenv is a great combo. As far as I can tell, like so many sources of frustration in tech, the issue typically lies with user error/not fully understanding the tool you're using. That isn't saying that there isn't room for improvement -- most notably, package management in Python flies in the face of "there should be one -- and preferably only one -- obvious way to do it" -- but the tools we have work quite well.
