The \"D:\\\\Python375\" part is suspicious, as it looks like the script has resolved the python interpreter's location to D:\Python375, which is highly unlikely - since this is Windows it should be pointing at python.exe. You should check to see what your environment is set up as, and make sure the build script can find python.
