I really thought that pipenv was an anti-pattern. How hard it is to run "python3 -m venv venv; source venv/bin/activate; pip3 install -r requirements.txt" that one needs to create a whole new tool just to combine these three simple commands together? If it is so hard to just use three commands, just put those three commands in a script or Makefile and move on.
I know pip has its own flaws with not-so-great package and dependency management. But does that warrant a whole new tool? Or does that warrant fixing the existing tool?
