Answer

You don’t have any compiler on your system, so PyPy can’t compile the packages.

notice the line error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/

Download the compiler with default settings and try again.
