Python 3.12: ModuleNotFoundError: No module named 'setuptools' #620
Description
The second and final Python 3.12 release candidate is out! 🚀
Call to action
We strongly encourage maintainers of third-party Python projects to prepare their projects for 3.12 compatibilities during this phase, and where necessary publish Python 3.12 wheels on PyPI to be ready for the final release of 3.12.0.
However, testing on Python 3.12.0rc2:
❯ tox -e py312

During handling of the above exception, another exception occurred:

from distutils.core import setup
ModuleNotFoundError: No module named 'distutils'

py312: FAIL code 1 (3.53=setup[3.52]+cmd[0.02] seconds)
evaluation failed :( (3.57 seconds)This will be due to the setuptools changes in Python 3.12:
easy_install,pkg_resources,setuptoolsanddistutilsare no longer provided by default in environments created withvenvor bootstrapped withensurepip, since they are part of the setuptools package. For projects relying on these at runtime, thesetuptoolsproject should be declared as a dependency and installed separately (typically, using pip).
