【问题描述】：
我正在尝试使用 kivy 制作应用，但我的许可被拒绝。我通过添加 ppa 并使用 sudo apt-get 在 kivy 网站上安装了 xubuntu 的推荐方式。当我运行应用程序时，会出现 GUI，但是当我按下一个应该返回一些文本的按钮时，GUI 会关闭，并且我收到一个错误，即我的类“MITMs1”没有属性“self”。我也在使用 scapy，我在 python 2.7 上。
这是一个类似的问题https://i11.at/dwl/eos/kivy30.pdf，但我的操作系统错误是
OSError: [Errno 13] Permission denied: '/dev/input/event5'
我的完整输出是
