I am facing an issue which has been discussed at length, and in many many forums, github issues, stack overflow questions, and so on.
To name a few:
Error in anyjson setup command: use_2to3 is invalid error in suds-jurko setup command: use_2to3 is invalid error in ibm_db setup command: use_2to3 is invalid Problem with simpleeval installation:use _2to3 invalid https://github.com/liftoff/pyminifier/issues/132 https://github.com/Thibauth/python-pushover/issues/42 https://github.com/odoo/odoo/issues/76144
For me installing or downgrading setuptools to a version less than setuptools<58.0 does not seem to fix the problem.
In order to test it I am creating a virtual environment using python3.7.9
(venv) ➜ headache git:(superbranch) ✗ python --version
Python 3.7.9
(venv) ➜ headache git:(superversion) ✗ pip --version
pip 23.1.2 from /local/venv/lib/python3.7/site-packages/pip (python 3.7)
The library in question is vatnumber==1.2 and no, I am not able to change that version, so I need to solve the build problem without changing the version of that dependency.
My setup tools are:
(venv) ➜ headache git:(superversion) ✗ pip show setuptools
Name: setuptools
Version: 57.5.0

And for completeness, this is the error

Running the same command using -vvv shows that when in a virtual environment a pip subprocess is initiated and setuptools is being upgraded to a version which does satisfy and internal vatnumber requirement, however it ignores the installed setup tool.

I would like to ask, if anyone has stumbled upon a similar situation, or if anyone can provide any help in order to dig deeper into the issue and solve the build problem. I have no way of pinning the setuptools version in this instance.
