   I start to see deprecation warnings in some unit test suites:

   babel/messages/checkers.py:160: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html
       from pkg_resources import working_set

   It is really bad because pybabel essentially does not work with python 3.12 with third party extractors.

   [python: **.py]
   [jinja2: templates/**.html]

   ValueError: Unknown extraction method 'jinja2'

   With python 3.11, it works ok.

   Can this be solved on Python >= 3.12 by doing pip install setuptools?

   https://docs.python.org/3/whatsnew/3.12.html

   gh-95299: Do not pre-install setuptools in virtual environments created with venv. This means that distutils, setuptools, pkg_resources, and easy_install will no longer available by default; to access these run pip install setuptools in the activated virtual environment.

   @cclauss thank you. It works, so it is good workaround for now.

   We are working on a patch to introduce fallback to importlib.metadata

   I also get the error ValueError: Unknown extraction method 'jinja2'. Installing setuptools via pip install setuptools doesn't solve this problem for me. I have tried it on MacOS 15.1 with Python 3.9 and ArchLinux with Python 3.12.

   Edit: I also tried to install setuptools with brew install python-setuptools (Mac) respectively sudo pacman -S python-setuptools (Linux), but that also doesn't help.

   Edit 2: I have found a workaround. Instead of directly using pybabel, I now use ./venv/bin/pybabel, which is working fine. :)

   I was also running into the error ValueError: Unknown extraction method 'jinja2' in an AlmaLinux 9 container within a Python 3.9 environment. Trying all the workarounds mentioned above did not work, but I found that specifying jinja2 as an extractor in the project's pybabel.ini file did the trick, so I'm including the example here just in case it might help someone else:

   [python: **.py]
   
   [jinja2: **.html*]
   
   [extractors]
   jinja2 = jinja2.ext:babel_extract

   I think this is resolved by #1102 (released in Babel 2.16.0 in 2024).
