Summary

beautysh v6.2.1 imports pkg_resources at the top level, which is part of setuptools. In Python 3.12+, setuptools is not included in new virtual environments by default (it was removed from the default venv seeding).

prek (and pre-commit) create isolated venvs per hook using uv. uv's venvs don't include setuptools by default, causing beautysh to fail with:

ModuleNotFoundError: No module named 'pkg_resources'

Adding additional_dependencies: [setuptools] tells prek/pre-commit to install setuptools alongside beautysh in its isolated venv, fixing the error.

Alternative

Bump beautysh to a release that removes the pkg_resources dependency, but the project appears unmaintained (last release 2022).
