Failed Building Wheel for mysqlclient with gcc.exe Error

I'm installing in the process of installing django on windows. I use WinPython 3.4.4.4 on Windows 64-bit. My MySQL Version is 5.6.32 according to Workbench.

When I did "pip install mysqlclient", I got "gcc.exe: error: /Zl: No such file or directory". Here is following log:

C:\WinPython-64bit-3.4.4.4Qt5\scripts>pip install mysqlclient
