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

Update a package: pip install --upgrade To update installed packages to the latest version, run pip install with the --upgrade or -U option.
Updating Pip You can update pip using pip without any hassle. When an update for pip is available, and you run a pip command, you will see a message that says, “You are using pip version xy. a, however version xy. b is available.” You can run “pip install --upgrade pip” to install and use the new version of pip.
Step 1: Download the get-pip.py (https://bootstrap.pypa.io/get-pip.py) file and store it in the same directory as python is installed. Step 2: Change the current path of the directory in the command line to the path of the directory where the above file exists. Step 4: Now wait through the installation process. Voila!
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 On Ubuntu 14 server, you also need to install libxft-dev
