Currently going through the python dependency hell. Very nice to read your response from Aug. 2022. There is hope! poetry add psychopy fails very hard on Debian 11. I’ve been using pyenv to try all versions from 3.8.13 onwards. No luck.
poetry groups are fantastic. But yeah, too new. Plus poetry is already proving to be slow at resolving large dependency trees, and imo will be replaced by something faster somewhere down the line. I’d definitely say packaging to pip is much more future-proof. That said, for now, I do use poetry and love the reproduceable builds it offers.
