It is a solved problem for other languages. Pip has soooo many issues.

The biggest IMO is pip doesn't provide a way to pin indirect dependencies, so there is no good way to ensure that other people working on a project are also using the same dependency versions. You can do it with extra tooling of course - and that's what poetry and pipenv do.

Even worse-- there's no simple way for pip to print out the full dependency tree (including transitive dependencies). This makes it a nightmare when it complains about some transitive dependency version conflict and you have no idea what's causing it to be pulled in

Isn’t this what pip freeze is for?

pip freeze only pins the version of direct, not transitive dependencies. Meaning you don't get deterministic builds.

I thought `pip freeze > requirements.txt` would give you a list of all dependecies, even indirect ones. Am I missing something?

I just so wish that Python tooling would be better, in large part pip is at fault here. If there was no conda I probably wouldn't even touch Python as things look very bleak especially if you need to run anything across different operating systems.
