I used pyenv in my previous company. At first it was fine, but after a while with multiple versions of Python installed, things stopped working. The right virtual env was not activated, etc. (It could have also been because our software updates like OS and security upgrades were pushed by desktop support). I removed all of it, and just resorted to installing multiple versions of Python the old way (downloading from python.org) and then use `python<version> -m venv /my/virtual/env` to manage my virtual environments. Things are more stable, and I don't feel like its magic. I am not going back to pyenv.
