Unsupported Python version

This version of Django REST Framework requires Python {}.{}, but you're trying
to install it on Python {}.{}.

This may be because you are using a version of pip that doesn't
understand the python_requires classifier. Make sure you
have pip >= 9.0 and setuptools >= 24.2, then try again:

    $ python -m pip install --upgrade pip setuptools
    $ python -m pip install djangorestframework

This will install the latest version of Django REST Framework which works on
your version of Python. If you can't upgrade your pip (or Python), request
an older version of Django REST Framework:

    $ python -m pip install "djangorestframework<3.10"
