Resolve ModuleNotFoundError: No module named 'wx'

[srfpala at gmail.com]

Running Win10 64-Bit and Pyscripter 3.3.2 Beta and/or VS 2017 with
Python 3.6.5 (v3.6.5:f59c0932b4, Mar 28 2018, 16:07:46) [MSC v.1900 32 bit (Intel)] on win32.
Interpreter sees import wx so will it attempt to find a specific file or reference to wx ?
Exactly what is the interpreter looking for?  
I thought an environment variable
D:\Python36\wxPython\site-packages  would resolve the issue  .. but I was wrong  !

Advice please
