Cannot run python on windows. What am I missing?

问题

I am pretty new to python. Please correct me if I show stupidity.

So I am trying to run the following code:

    from gi.repository import Gtk
class LisaMainWindow:

  def on_LisaMainWindow_destroy(self, object, data=None):
    print ("quit with cancel")
    Gtk.main_quit()

  def __init__(self):
    self.gladefile = "lisaMainWindow.glade"
    self.builder = Gtk.Builder()
    print ("gtk builder done")
    self.builder.add_from_file(self.gladefile)
    print ("glade loaded")
    self.builder.connect_signals(self)
    self.window = self.builder.get_object("lisaMainWindow")
    self.window.show()

if __name__ == "__main__":
  main = Buglump()
  Gtk.main()

And I get the following error

** (python.exe:6388): WARNING **: Failed to load shared library 'libgtk-3-0.dll'
 referenced by the typelib: 'libgtk-3-0.dll': The specified module could not be
found.

** (python.exe:6388): WARNING **: Failed to load shared library 'libgdk-3-0.dll'

I am running Windows 8 on 64 bit. Below are my installations to develop a Gtk based GUI.

python-3.4.3.amd64.msi from https://www.python.org/downloads/windows/
pygi-aio-3.14.0_rev10-setup.exe from http://sourceforge.net/projects/pygobjectwin32/files/

What am I missing or doing wrong ? Please help. (thanks in advance)

I just had the same kind of problem.

To solve it, I have installed GTK3+ from http://www.gtk.org/download/win32.php the all-in-one bundle of the GTK+ stack including 3rd-party dependencies at http://win32builder.gnome.org/gtk+-bundle_3.6.4-20130921_win32.zip after unzip the file in somedir.

You can test it by running somedir\bin\gtk3-demo.exe you have to add the bin dir which contains dll files in the windows PATH run in console > where libgdk-3-0.dll to check dll are found then run your python file.
