Error in anyjson setup command: use_2to3 is invalid

#25 3.990   × python setup.py egg_info did not run successfully.
#25 3.990   │ exit code: 1
#25 3.990   ╰─> [1 lines of output]
#25 3.990       error in anyjson setup command: use_2to3 is invalid.
#25 3.990       [end of output]

This is a common error which the most common solution to is to downgrade setuptools to below version 58. This was not working for me. I tried installing python3-anyjson but this didn’t work either. I’m at a complete loss.. any advice or help is much appreciated.

If it matters: this application is legacy spaghetti and I am trying to polish it up for a migration. There’s no documentation of any kind.

Answer

Downgrading setuptools worked for me

pip install "setuptools<58.0.0"

And then

pip install django-celery
