How do people install stuff like this? So many tools these days use `npm install` or `pip install`. I certainly have npm and pip installed but they're sandboxed to specific projects using a tool like devbox, nix-devshell, docker or vagrant (in order of age). And they'll be wildly different versions. To be pedantic `pip` is available globally but it throws the sensible `error: externally-managed-environment`

I'm sure there's a way to give this tool it's own virtualenv or similar. But there are a lot of those things and I haven't done much Python for 20 years. Which tool should I use?
