Current pip version 20.0 is broken - see https://github.com/pypa/pip/issues/7620

Install pip other than 20.0:

$ pip install -U "pip!=20.0"

Update: pip 20.0.1 was released that fixes this issue.

If you are stuck with 20.0 and cannot upgrade to 20.0.1 because of this error, try get-pip.py or easy_install.

$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
$ python get-pip.py --ignore-installed
