Python/pip failed installing Matplotlib

I have Python 3.8 installed, I was able to install numpy and scipy flawlessly. When I try to install matplotlib I get this output in my command prompt. 

    building 'matplotlib.ft2font' extension
    creating build\temp.win-amd64-3.8

I have no idea how to fix this, I've updated pip and I have also tried to install from a .whl file but still no dice.

Any help is greatly appreciated.

EDIT: If you want the full command prompt output I made a pastebin with it here: https://pastebin.com/HNXcGrDH

Download the prebuilt lib from Prof. Gohlke and install using pip

https://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib

pip install matplotlib-3.1.1-cp38-cp38-win_amd64.whl

You are missing the freetype library that is a dependecy of matplotlib Take a look at this repo for building the required libraries for matplotlib. Note however that the latest release of matplotlib does only support python 3.7. You might still be able to build from source if you use the latest version from github, but there is no guarantee for its stability, esspecially since there are currently no official tests of matplotlib for python 3.8
