#118 iPython raise ImportError for PyGObject/PyGi

[Chickenmarkus]

Once again I have to program scientific software. But this time it has to run on a measuring computer with Windows. For this purpose I've installed WinPython 3.3.5 (32 bit) and PyGObject 3.12.2 with GTK+3.8.9 (32 bit).

WinPython Interpreter works:

Python 3.3.5 (v3.3.5:62cf4e77f785, Mar  9 2014, 10:37:12) [MSC v.1600 32 bit (In
tel)] on win32

>>> import gi
>>>

WinPython Command Prompt works too:

The normal Windows' cmd.exe works too:

But IPython Qt Console doesn't:

On the one hand iPython is very useful and on the other hand py2exe/cx_Freeze also doesn't find gi module on every console with similar message.

[Chickenmarkus]

import gi works in IPython from WinPython 3.3.2.3 (32 bit). No more time to try from which version it no longer works. Next step is to get GTK+3 working with cx_Freeze.
