Question

我在Windows上安装了Pygobject，当我尝试运行此代码时：

#!/usr/bin/python
from gi.repository import Gtk

class StackWindow(Gtk.Window):

    def __init__(self):
        Gtk.Window.__init__(self, title="Stack Demo")
        self.set_border_width(10)

        vbox = Gtk.Box(orientation=Gtk.Orientation.VERTICAL, spacing=6)
        self.add(vbox)

        stack = Gtk.Stack()
        stack.set_transition_type(Gtk.StackTransitionType.SLIDE_LEFT_RIGHT)
        stack.set_transition_duration(1000)

        checkbutton = Gtk.CheckButton("Click me!")
        stack.add_titled(checkbutton, "check", "Check Button")

        label = Gtk.Label()
        label.set_markup("<big>A fancy label</big>")
        stack.add_titled(label, "label", "A label")

        stack_switcher = Gtk.StackSwitcher()
        stack_switcher.set_stack(stack)
        vbox.pack_start(stack_switcher, True, True, 0)
        vbox.pack_start(stack, True, True, 0)

win = StackWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()

我收到错误消息：

Warning (from warnings module):
  File "F:\ASM_Archive\gui01.py", line 13
    stack = Gtk.Stack()
Warning: cannot retrieve class for invalid (unclassed) type 'void'
Traceback (most recent call last):
  File "F:\ASM_Archive\gui01.py", line 29, in <module>
    win = StackWindow()
  File "F:\ASM_Archive\gui01.py", line 13, in __init__
    stack = Gtk.Stack()
TypeError: could not get a reference to type class

这是否意味着我安装了错误或错过了什么？我可以创建窗口，添加按钮等，但当我尝试添加更多类似于＆＃39; Gtk.Stack（）＆＃39;或者＆＃39; Gtk.ListBox（）＆＃39;我有错误。

＆＃39;无法检索有效（未标记）类型的课程＆＃39; void＆＃39;＆＃39;在Pygobject？
