I found it is wired that if I use Python 3.6 in vs2015, the search paths will be useless. Python will show me "No module named 'xxx'"
And after I change python environment to 3.5, my source code can execute well.
What I have done is according to this reference:. And it is actually OK when the environment is 3.5. Is this a bug for visual studio? Thank you :-)
