Numpy install Broken toolchain: cannot link a simple C program

System:

Windows 10
Python 3.7
Numpy 1.15.1
VS 2017

I don't believe this is a duplicate as the following proposed resolutions have failed:

Additional Note: I don't have network access so I'm using 'basket' my install line is as follows:

pip install --no-index -f .basked numpy

I've run this in the command prompt, power shell, and VS command prompt

Final Error in Traceback:

 377, in generate_sources
        source = func(extension, build_dir)
      File "numpy\core\setup.py", line 666, in get_mathlib_info
        raise RuntimeError("Broken toolchain: cannot link a simple C program")
    RuntimeError: Broken toolchain: cannot link a simple C program

I just answered the exact same question here: https://stackoverflow.com/a/61563861/209532

In short: You need to have mt.exe on the path to compile, Since Visual Studio 2017, is has been removed and is now to be found in the Windows SDK.
