Problem on windows system

[Fliptron]

Hi,
I am trying to learn Sphinx, and using your tutorial. During the setup phase, I got the following

(env) D:\2019\Docs_for_PyOCD\richdaydocs>pip install -r requirements.txt

..... lots of stuff that installed fine , then

Requirement already satisfied: colorama>=0.3.5; sys_platform == "win32" in d:\2019\docs_for_pyocd\env\lib\site-packages (from Sphinx==1.7.5->-r requirements.txt (line 29)) (0.4.1)

Failed to build mysqlclient

So this probably means I would have problems running the actual tutorial project, but I should be fine with the Sphinx stuff that I care about.

FYI, My system is Windows 7 Pro x64

Thanks,
