ubuntu 14.04, pip cannot upgrade matplotllib

Question

When I try to upgrade my matplotlib using pip, it outputs:

Downloading/unpacking matplotlib from https://pypi.python         


        

Answer 1

I had the same issues trying to install matplotlib on Python 3 using pip3, and it seems that this problem is related to a bare-bones installation of Python 3, and doing a:

sudo apt-get build-dep matplotlib

followed by

sudo pip3 install matplotlib 

is probably a better solution than selectively installing only the libraries related to matplotlib.
