I'm getting a bunch of user facing errors because setuptools is depreciating something.

The message being spammed at me: 

/usr/lib/python3.13/site-packages/class_registry/entry_points.py:3: UserWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources package is slated for removal as early as 2025-11-30. Refrain from using this package or pin to Setuptools<81.
  from pkg_resources import iter_entry_points

I have verified that class-registry has fixed this problem in 4.1.0, would you mind upgrading?

@2bluesc: Thanks for the tip! I should have tried this first before reaching out. It looks like my python-class-registry package was still in Python 3.9, while I upgraded to 3.10 several weeks ago. Forcing a rebuild of both backblaze-b2 and python-class-registry fixed the problem for me, I was able to authorize my account without having to move .b2_account_info (it didn't exist on my target laptop).

The package name in PyPi is phx-class-registry, not sure if that matters.

@ectospasm I don't think there's a bug here as I can't recreate the issue, this package name (and backblaze-b2 requirements.txt) hasn't been changed in 2+ years and many backblaze-b2 users seem to not have issues.

I just tested backblaze-b2 authorize-account on my account after deleting my ~/.b2_account_info and it works without issue.

You should check that your environment and make sure you have this package correctly installed.

Test cases:

$ python3 -c 'import class_registry; print(class_registry.__file__)'

/usr/lib/python3.10/site-packages/class_registry/__init__.py is owned by python-class-registry 3.0.5-1

Tried loading the phx-class-registry distribution directly and it seems happy as well:

python3 -c 'from importlib.metadata import distribution; print(distribution("phx-class-registry").files)'

It appears this package has been renamed to phx-class-registry. backblaze-b2 requires this package at the new name, see the following Python Traceback:

'python-setuptools' is missing from makedepends
