For some reason I can\'t explain or google, py2app crashes on me even with the simplest examples. Im using a python 3.4.1 virtual environment created as Projects/Test/virt
I had the same problem as you and solved it now.
I referred to this post.
First, search for the path
$ /yourenv/lib/python2.7/site-packages/py2app/recipes/virtualenv.py
Next, open this file virtualenv.py, look for scan_code or load_module and change it to _scan_code or _load_module.
Last, try to run your app
