Re: [Matplotlib-users] Failing to install matplotlib with python 3

[Eric F. <ef...@ha...>]

Alan,

This mailing list is obsolete; please use mat...@py....

Your traceback looks vaguely familiar as something that has come up 
before, but I don't have any more recollection than that.  Suggestions:

1) Install your python environment the easy way via anaconda or 
miniconda: https://www.continuum.io/downloads

2) If you are *sure* you don't want to do it that way, make sure you 
have the most recent version of pip.

3) Likewise, install the most recent matplotlib.  See attached message.
