我正在尝试在 OSX 上运行位于此处的简单 Kivy 应用程序。
起初，CEF 在初始化期间失败。输出是：

Trace/BPT trap: 5
我在这里找到了一个讨论，建议手动设置local_pak标志以避免此错误。从第 150 行开始，我对示例代码进行了以下更改：
# Command line switches set programmatically
g_switches = {
"locale_pak": cefpython.GetModuleDirectory()
+"/Resources/en.lproj/locale.pak",
}
#init CEF
cefpython.Initialize(settings, g_switches)
这解决了我的初始化问题！CEF 浏览器出现，但不会响应我键盘的任何输入。我也无法使用触控板滚动，尽管我可以使用它来点击链接。
我给出了这个问题的全部背景，以防我通过更改locale_pak标志走错了路。
我在用着：
Kivy v1.9.0
Python v2.7.6
cefpython3 v31.2
我还应该提到，我能够毫无问题地运行wxpython.py打包的示例。cefpython3
任何帮助将不胜感激！
