Building executables for Python 3 and PyQt

Question

Hi all.

I built a rather simple application in Python 3.1 using PyQt4. Being done, I want the application to be distributed to computers without either of those installed.

I almost exclusively care about Windows platforms, so my goal is to have a single executable file and maybe some resource files and .dlls in the end.

Having searched around, I came to the conclusion that

• py2exe only supports Python up to version 2.7
• pyinstaller only supports Python up to version 2.6
• cx_Freeze does not work for me because I keep on getting the following error when trying to execute my successfully build binary:

Y:\Users\lulz\build\exe.win32-3.1>system_shutdown.exe

Traceback (most recent call last):

    File "Y:\Program Files (x86)\Python\lib\site-packages\cx_Freeze\initscripts\Console3.py", line 27, in  exec(code, m.__dict__)

    File "Y:/Users/lulz/Documents/Coding/Python3/projects/System Shutdown/system_shutdown.pyw", line 5, in  from PyQt4 import QtCore

    File "ExtensionLoader_PyQt4_QtCore.py", line 16, in  AttributeError: 'NoneType' object has no attribute 'modules'

So my problem is basically two problems here:

1. Is there another way but cx_Freeze to build binaries with my configuration?
2. If not, what might the cx_Freeze problem be?

I can provide more information on the second problem if necessary, like my call of cx_Freeze, my distutils setup script etc.

Thank you already for your help and comments.

You can fix this by appending one line of code to freeze.py in your cx_Freeze package.

It worked for me at least :)
