  Unsupported Python version
  ==========================
  This version of urllib3 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 urllib3
  This will install the latest version of urllib3 which works on your
  version of Python. If you can't upgrade your pip (or Python), request
  an older version of urllib3:
      $ python -m pip install "urllib3<2"
