`poetry install` fails

[cthoyt]

I'm on an m3 mac running mac os 14. I installed poetry with uv tool install poetry.

$ poetry --version
Poetry (version 1.8.4)

I got the following error while trying to install. This seems like an old version of pydantic-core

$ poetry install
Installing dependencies from lock file

When I have this it's a problem with Python version. Try using Python 11 as a base version and see if it works, this does not close the issue, just helps moving your exploration forward

I only reproduce the error with Python 3.13 on a Apple Silicon machine, up to commit c09299b.

Commit d8a2c93, which (as a side-effect) bumped pydantic-core to version 2.23.4, fixes the issue for me, regardless of the version of Python.
