在https://github.com/cztomczak/cefpython/blob/master/src/linux/binaries_64bit/kivy_.py中，pygtk并被gtk使用。（注意源代码只在Linux下测试过，我用的是Windows）

当我尝试时pip install pygtk，出现错误

因此，我又去了pip install pygobject，错误。

然后我参考了一些关于 stackoverflow 的帖子，他们告诉我gtk不再需要它，python3并将其替换为pgi. （我不知道我应该在源代码中替换pygtkor gtk）所以我尝试了pip install pgi，再次出错。

我不知道发生了什么。我希望有人能把我从这个无限错误循环中拉出来。非常感谢。

首先我要提一下我使用的是Xubuntu 20.04，所以是Linux。

为了使 kivy 示例正常工作，您需要将 pygtk 模块替换为 PyGobject 模块。所以安装它，这里是说明：

https://pygobject.readthedocs.io/en/latest/getting_started.html#windows-logo-windows

现在在这个文件中 https://github.com/cztomczak/cefpython/blob/master/src/linux/binaries_64bit/kivy_.py你需要更改导入和其他一些东西。这是我的进口商品的样子

...

from cefpython3 import cefpython as cef

import gi       # notice this line is added
# import pygtk  # this one is commented out or you can delete it
from gi.repository import Gtk as gtk    # this one is added
# import gtk    # this one is commented out or you can delete it
import sys

...

from kivy.graphics.texture import Texture
from kivy.uix.boxlayout import BoxLayout
from kivy.base import EventLoop

# Global variables
g_switches = None

# PyGTK required
# pygtk.require('2.0') # this one is commented out or you can delete it


class BrowserLayout(BoxLayout):
...

我还需要修复传递给windowInfo.SetAsOffscreen在第 208 行附近调用的方法的参数（在我的情况下），查找start_cef方法定义。我根据这个https://github.com/cztomczak/cefpython/blob/master/api/WindowInfo.md#setasoffscreen将参数设置为 0，因为它提到：

您可以将 0 作为 parentWindowHandle 传递，但是上下文菜单和插件等某些内容可能无法正确显示。

所以代码看起来像这样：

...
#popup widgets to work.
gtkwin = gtk.Window()
gtkwin.realize()

# WindowInfo offscreen flag
windowInfo = cef.WindowInfo()
windowInfo.SetAsOffscreen(0)
    
# Create Broswer and naviagte to empty page <= OnPaint won't get
# called yet
...
