Answer 1

It looks like setuptools>=58 breaks support for use_2to3:

setuptools changelog for v58

So you should update setuptools to setuptools<58 or avoid using packages with use_2to3 in the setup parameters.

I was having the same problem, pip==19.3.1

Answer 2

Upgrading MongoEngine to >= 0.20 would also fix the problem as Python2 support (hence use_2to3) was dropped in 0.20

Answer 3

I install setuptools==58It worked for me. pip install setuptools==58. The error coming from setuptools==69 that previously run on my device. and Finally saved me setuptools version 58 for this error.

Answer 4

"pip install setuptools==58" worked for me. The setuptools version was 59 when I upgraded ubuntu to 22.04 and its python 3.10. I started a clean virtual environment for an existings django project. It had just two packages:

`pip list
Package Version

pip 22.0.2
setuptools 59.6.0`

Then I downgrade the setuptools to 58 as pip install setuptools==58.0.0. After that the pip install -r requirements.txt has not such error above.

I’m working on Windows 11 and these solutions didn’t work. I installed pybluez2 instead. Your python version >= 3.9 on Windows.

pip install pybluez2
