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

Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.
Method 1
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
Method 2
On Ubuntu 14 server, you also need to install libxft-dev
sudo apt-get install libfreetype6-dev libxft-dev
Method 3
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.
Method 4
Since mac doesn’t have apt-get you, on OSX you may need to do:
brew install freetype
then you can run:
pip install matplotlib
Method 5
Found this page while looking answer for fedora 24.
RPM solution is:
dnf install freetype-devel
Method 6
If you re running Ubuntu server 14.04 u should add this font dependency
sudo apt-get install libxft-dev
Method 7
I was trying too update directly using sudo pip but changes are not saved in last. So i first use update cmd in terminal:
sudo apt-get update
then i used sudo install:
sudo apt-get install libffi-dev
Finally its installed by doing this method.
Method 8
For those on Fedora 25 hitting this thread, I needed these two packages to make it work:
sudo dnf install freetype-devel gcc-c++
Method 9
This worked for me:
python -m pip install -U pip setuptools python -m pip install matplotlib
