Today I just finished a complex program that I never do before, hence I cannot use the inner ghpython editor to debug it. I have tried following the tutorial step by step: Debugging GhPython components Visual Studio with Python (rhino3d.com), but I encountered this problem in STEP 7. My GHPythonDebug.py is here GHPythonDebug.py (537 Bytes).
I never see an error message like this and I find out that the same message would be sent when I open Python script editor similarly. Restart Rhino, GH or VSstudio seems useless. I hope someone can offer some help to solve the problem.
