Python 3.3 cx_freeze weird error: 'NoneType' object has no attribute 'path'

So, here's my problem.

I'm making a game in Pygame and Python 3.3, using Ubuntu 12.10. Fine. I'm gonna bundle a bunch of Python scripts into one executable, then distribute it. Also fine. I'm going with cx_freeze, because since I'm using Python 3 I have no other options.

This is where my problem comes in. I've Googled around, but haven't seen anything like it. My setup.py is as follows:

from cx_Freeze import setup, Executable
import sys

includes = ['sys', 'pygame.display', 'pygame.event', 'pygame.mixer', 'core', 'game']

build_options = {
                 'optimize' : 2,
                 'compressed': True,
                 'packages': ['pygame', 'core', 'game'],
                 'includes': includes,
                 'path': sys.path + ['core', 'game'],
                 }

executable = Executable('__init__.py',
                        copyDependentFiles=True,
                        targetDir='dist',
                        )

setup(name='Invasodado',
      version='0.8',
      description='wowza!',
      options = {'build_exe': build_options},
      executables=[executable])

My __init__.py is as follows:

from sys import argv

import pygame.display
import pygame.event
import pygame.mixer

pygame.mixer.init()
pygame.display.init()
pygame.font.init()

from core import gsm

#Omitted for brevity

The rest of my code (including the full __init__.py) can be found at https://github.com/CorundumGames/Invasodado, in case it's relevant.

I get a long-ass stack trace, which can be found here http://pastebin.com/Aej05wGE . The last 10 lines of it is this;

  File "/usr/local/lib/python3.3/dist-packages/cx_Freeze/finder.py", line 421, in _RunHook
    method(self, *args)
  File "/usr/local/lib/python3.3/dist-packages/cx_Freeze/hooks.py", line 454, in load_scipy
    finder.IncludePackage("scipy.lib")
  File "/usr/local/lib/python3.3/dist-packages/cx_Freeze/finder.py", line 536, in IncludePackage
    self._ImportAllSubModules(module, deferredImports)
  File "/usr/local/lib/python3.3/dist-packages/cx_Freeze/finder.py", line 211, in _ImportAllSubModules
    recursive)
  File "/usr/local/lib/python3.3/dist-packages/cx_Freeze/finder.py", line 209, in _ImportAllSubModules
    if subModule.path and recursive:
AttributeError: 'NoneType' object has no attribute 'path'

In case it's relevant, I'm using Pydev and Eclipse. Now, the last line stands out because Googling it reveals nothing. I have no idea where subModule could have become None, and I can't easily check because cx_freeze has shit documentation.

I've never really used cx_freeze or distutils before, so I don't know what the hell I'm doing! Any help would be greatly appreciated.

Solution

  • Having dug into this, it's a bug in cx_Freeze, that can only hit when you have more than one Python version since PEP 3149 installed - i.e. it wouldn't have come up before 3.3.

    I've filed a bug report for it: https://bitbucket.org/anthony_tuininga/cx_freeze/issue/22/error-when-scanning-for-modules-with-a

    In the mean time, you can probably avoid the problem by using Python 3.2 for now, because that's the default in Ubuntu 12.10. Python 3.3 will be the default in 13.04.
