Mac App refer to Python executable

I wanted to refer to a Python shipped with an app: /Applications/FreeCAD.app/Contents/lib/Python

But Wingware won't let me

Some values are invalid:

  • Could not launch or inspect Python executable '/Applications/FreeCAD.app/Contents/lib/Python'. It should be the name of a Python interpreter that is on your PATH (such as python, python3.4, python.exe), a full path to the Python interpreter you wish to use, or a command line that invokes Python with any appended arguments.

Please correct the values and try again.

I'd rather guess this is some silly Mac security feature. However, how do I get rid of it and refer to the app's executable (without having to copy it to some local directory)?

Hmm. I tried to run this from command iine and there it croaks that it's not a valid executable. Strange, but likely no Wingware issue. The bug in front of the keyboard needs to think....

It's possible that the app loads Python dynamically. If you are able to get a Python shell in the app, try this:

import sys
print(sys.executable)

Using that executable might work, but there's no real guarantee that there is a regular Python installation in there.

If not, you may still be able to debug Python code running in the app as described here:
