Installation Errors - is there a Visual Studio dependency?

[EngrStudent]

I used installation directions here:
https://spitfire.readthedocs.io/en/latest/?badge=latest

When I tried to do this: pip install .

I got this:

Preparing metadata (setup.py) ... error

  note: This error originates from a subprocess, and is likely not a problem with pip.

When I got to here:
python3 -m unittest discover -s tests

It gave me lots of errors:

Scrolling back through previous steps, I found this:

C:\Windows\System32>type "C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\\VC\Auxiliary\Build\Microsoft.VCToolsVersion.default.txt"
The system cannot find the path specified.

C:\Windows\System32>dir "C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\\VC\Redist\MSVC\"
The system cannot find the path specified.

Questions:

• Does this require a pre-installed version of Microsoft Visual Studio in order to operate?
• Is this suggesting that I have some version of VS that is not running properly?
