Answer 1

Try to install Visual Studio, here: https://visualstudio.microsoft.com/. Often, packages depend on Visual Studio for compilers and other items.

It appears it terminates because running the below command:

error: command 'C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.28.29333\bin\HostX86\x86\cl.exe' failed with exit status 2

failed. Installing Visual studio may fix this.
