Undeclared runtime dependency on setuptools/pkg-resources

[edwardpeek-crown-public]

Problem

Importing model_utils in a python environment that does not have setuptools installed fails with error:

  ...
  File "REDACTED/venv/lib/python3.9/site-packages/model_utils/__init__.py", line 1, in <module>
    from pkg_resources import DistributionNotFound, get_distribution
ModuleNotFoundError: No module named 'pkg_resources'

but setuptools is not listed under install_requires in setup.py.

This can occur when using the pip options --prefix, --root, --target to use different python environments between install/runtime.

Environment

• Django Model Utils version: 4.1.1 / HEAD
• Django version: 3.2.4
• Python version: 3.9
• Other libraries used, if any: setuptools absent

I just had this, for reference I installed model utils using pdm 😊

#545 replaced pkg_resource with importlib
