+1. On top of that, even with the new resolver it still takes ages to resolve a dependency for me, so somethimes I end up just using pip directly. Not sure if I am doing something wrong(mb you have to manually tweak something in the configs?) but it's pretty common for me to experience this
Like sibling comments,
after using poetry for years (and pipx for tools), I tried uv a few months ago
I was so amazed of the speed, I moved all my projects to uv and have not yet looked back.
uv replaces all of pip, pipx and poetry for me, I does not do more than these tools, but it does it right and fast.
If you're at liberty to try uv, you should try it someday, you might like it.
(nothing wrong with staying with poetry or pyenv though, they get the job done)
I believe the problem is the lack of proper dependency indexing at PyPI. The SAT solvers used by poetry or pdm or uv often have to download multiple versions of the same dependencies to find a solution.
