When python pip Spoils the Party

Your old version of pip tells you :

You should consider upgrading via the 'python -m pip install --upgrade pip' command.

Then, when you try :

$ python -m pip install --upgrade pip

/usr/bin/python: No module named pip

Thank you Guido!

Fortunately, googling got me

$ pip install -U pip

threw out a tonne of errors about permissions (this is Cygwin), but seems to be working okay..

$ pip --version       makes me happy
