https://pypi.org/project/anyjson/ has not been released since 2012 and its installation utilizes `use_2to3=True` which was [removed in `setuptools` v58.0.0](https://setuptools.pypa.io/en/latest/history.html#v58-0-0) because `2to3` is being removed from Python. Workaround: Downgrading via `pip install "setuptools<58.0.0"` should enable `django-celery` to be installed.
