I'm getting a CompileError when running a simple PyStan model in Python:

I've isntalled Pystan using pip (pip install PyStan) on Python 3.6 and am trying to run a simple model (first example here)
I have both MS Visual Studio (not supported) and MinGW-64 (supported) installed on my PC. MinGW works fine to compile similar models using PyMC3, so it seems to me I just need to get my Pystan package to recognize the installation and use that compiler instead. Unfortunately even if that is correct, I am not sure how to do that, can someone help?
