Stuck in installing matplotlib on Win 10

abdu · October 29, 2019, 11:06am

Hi,

I am trying to install matplotlib for the past 3 days on Windows 10. I got errors about VS Build Tools, uninstalled and reinstalled C++ redist almost any version. Finally, installing Visual Studio fixed the problem but then started getting errors about Freetype. I added the ft2build.h and freetype.lib locations to system environment and still got problems so I moved all the files in python38-32/include.

Now I have a different error. Here is the last part I can copy from the command window (I tried to find the full log file, bu not luck.) :

I installed this in a much easier way. Could not fix the problem above though.

So if you are stuck like me, I did the following:

Make sure Python and C++ redist is installed.
Go to https://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib and download relevant WHL file.
pip install downloadedfile.whl

Voila!

Just went through installing on Win 10 from source, and what worked for me (besides having visual studio installed) was making sure that in setup.cfg the following was set:

[libs]
# By default, Matplotlib downloads and builds its own copy of FreeType.  You
# may set the following variable to True to instead link against a system
# FreeType.
system_freetype = False
