I am trying to use matplotlib in Python but any imports fail with the following error:
from matplotlib.backends.backend_gtk3cairo import FigureCanvasGTK3Cairo as FigureCanvas
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python27\lib\site-packages\matplotlib\backends\backend_gtk3cairo.py", line 6, in <module>
from . import backend_gtk3
File "C:\Python27\lib\site-packages\matplotlib\backends\backend_gtk3.py", line 21, in <module>
"Gtk3 backend requires the GObject introspection bindings for Gtk 3 "
ImportError: Gtk3 backend requires the GObject introspection bindings for Gtk 3 to be installed.
The application needs to be able to run on Windows machines. Does anyone have any support on this?
I have found a lot of old threads that say it is impossible to use GTK3 and Python on Windows, but they are at least 2-3 years old. So things might have changed since then.
Solved by using the pygi-aio installer from http://sourceforge.net/projects/pygobjectwin32/files/pygi-aio-3.14.0_rev22-setup.exe and uninstalling any other older dependencies (GTK2, pygobject, etc)
