Trying a Windows 10 Build of Carla (0.9.13) - Getting Fatal error when trying to make PythonAPI

[mspring6]

Hello, I am getting this issue when trying to build CARLA from source on Windows 10, specifically when making the PythonAPI. It says there is a fatal error, console output can be found below, and the carla lib is not actually installed and cannot be found in the /carla/dist directory. I was hoping someone has seen this error before and knows how to fix it?

Output from console:

Hi @mspring6,

this is a very common error that occurs when you have more than one Python version on your machine. Make sure that the commands py -3, py and python in your command line all call the same Python version. If this is not the case you may want to replace all occurences of py in the Carla build scripts with python.
