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

Found this page while looking answer for fedora 24.

RPM solution is:

dnf install freetype-devel

Answer 2

This is a known bug that has been fixed (https://github.com/matplotlib/matplotlib/pull/3414) on master.

The bug is in the handling of searching for a freetype installation. If you install the Linux package freetype-dev, you will avoid this bug and be able to compile matplotlib.

sudo apt-get install libfreetype6-dev

Answer 3

If you re running Ubuntu server 14.04 u should add this font dependency

sudo apt-get install libxft-dev
