问题描述
我尝试在互联网上遵循多种解决方案，也this 一种，但没有成功。我正在实施对象检测系统。我在 Windows 10 上，使用 python-3.8 使用 PyCharm
我收到软件包错误，我尝试通过软件包安装程序和终端添加它们，但没有成功。这是错误：
Traceback (most recent call last):
File "D:/CabaleGame/runner.py",line 2,in <module>
import processCards
File "D:\CabaleGame\processCards.py",line 1,in <module>
import gtk.gdk
ModuleNotFoundError: No module named 'gtk'
Process finished with exit code 1
我已经从 here 和 here 下载了软件包，哪个是正确的？

是否可以通过文件夹手动添加？ 如果我把包裹交给她，它会起作用吗：
C:\Users\User1\AppData\Local\Programs\Python\python38\include
解决方法
来自 python 文档：
将 import gtk.gdk 替换为：
import gi
gi.require_version("Gtk","insert your gtk version")
from gi.repository import Gtk
