pip install jupyter: "Unable to locate finder for 'pip._vendor.distlib'"

I'm trying to install

jupyter
to use the IPython Notebook under Windows. However, if I run
pip install jupyter
I'm getting

Any idea what the problem here is?

Answer

Try uninstalling pip and installing get-pip.py. It appears to be a bug in the 3.6 version for Windows. https://github.com/pypa/pip/issues/3964
