Problem

Using the [http://www.jorendorff.com/articles/python/path/ 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 [http://www.stackless.com/ 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.py

and to delete path.pyc and path.pyo from your site-packages directory.
