@CodeMonkey @ertai No it is not perfectly usable for all people, all projects, all situations. uv definitely gets much closer to that.

it's usable, yet it doesn't attempt to solve a a third of the problems uv, poetry, and pdm address.

it's also not hard to end up with a broken env with pip.

Except that it’s slower than uv and therefore strictly worse for build processes

Putting aside the speed uv has a bunch of features that usually require 2-4 separate tools. These tools are very popular but not very well liked. The fact these tools are so popular proves that pip is not sufficient for many use cases. Other languages have a single tool (e.g. cargo) that are very well liked.
