Problem
Using the PathModule from Jason Jorendorff, modulefinder.py, which is called by Py2Exe, gets into an endless recursion.
It tries to resolve os.path, gets to os.os.path , further to os.os.path and breaks somewhere at os.os.os.os.os.os.os.os.os.os.os.os.os.os.os.os.os.os.os.os.os.os.os.os.os.os.os.path at which point you get a RuntimeError: maximum recursion depth exceeded.
(Maybe it would be a test to use StackLess Python, it would run forever or until the maximum string length of pyhton is reached. But maximum string length in Python is only limited by memory, memory is limited by address-space ... )
But apart from joking: it is IMPOSSIBLE to generate an exe with the modern 0.5 Version of Py2Exe when path.py is installed.
Workaround
Just rename
site-packages/path.py
to
site-packages/jpath.py
and make sure also to toggle your imports to
1 import jpath
and to delete path.pyc and path.pyo from your site-packages directory.
