I recently tried to use py2app and I have a simple app named test.py. everything is fine, until I type 'python3 setup.py py2app'. here is the error message:

I'm using python3.6 on macOS sierra.
There is a reported python bug that was caused by Apple no longer installing open SSL. See this discussion.
