Python2.7: ImportError: six 1.3 or later is required; you have 1.2.0

Question

Got this error when importing matplotlib.pyplot. But I have checked the version of six installed using pip list, and it returns version 1.9.0. And when I checked six.__version__, it returns 1.2.0.

Could any one help me?

Answer 1

There is probably a bug somewhere, but a quick and dirty work around was the following:

pip install six==1.8.0
