This is why I decided to learn Nix. I built dev environment flakes that provision the devshell for any language I intend to use. I actually won’t even bother unless I can get something working reliably with Nix. ;)

For example, here’s a flake that I use for my Python dev environment to provide all needed wiring and setup for an interactive Python web scraper I built:
