Fix Python 3 on Windows error Microsoft Visual C++ 14.0 is required

Fix the error for Python 3.6 and 3.7 on Windows:

error Microsoft Visual C++ 14.0 is required

as follows. It requires about 6 GB of disk space (for Visual Studio Studio 2017 Build Tools).

1. Install using any ONE of these choices:
   • Microsoft Build Tools for Visual Studio 2017.
   • Alternative link to Microsoft Build Tools for Visual Studio 2017.
   • Offline installer: vs_buildtools.exe
2. Select: Workloads → Visual C++ build tools.
3. Install options: select only the “Windows 10 SDK” (assuming the computer is Windows 10)

Notes

Python version	Visual Studio
2.7, 3.4	2010
3.5	2015
3.6, 3.7	2017

Why Visual C++?

Windows Python needs Visual C++ libraries installed via the SDK to build code, such as via setuptools.extension.Extension or numpy.distutils.core.Extension. For example, building f2py modules in Windows with Python requires Visual C++ SDK as installed above. On Linux and Mac, the C++ libraries are installed with the compiler.
