问题
I am attempting to get Python.net (pythonnet) working on Python 3.7 and when running the setup.py it fails with the following error. I'm assuming that it has to do with a missing entry in the path lines but I coulnd't fine any reference to it. It's basically a pretty plain install of Python 3.7 on Windows 7. the pip install also fails with the same results. Does anyone have a suggestion on what path or file might be missing?
PS C:\Users\user\pythonnet-master\pythonnet-master> python setup.py bdist_wheel
running bdist_wheel
running build
running build_ext
