我试图用kivy制作应用程序，但我的许可被拒绝了。我通过添加ppa和使用sudo apt-get在kivy网站上为xubuntu安装了推荐的方法。当我运行应用程序时，GUI会出现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，我的班级＆＃39; MITMs1＆＃39;没有属性＆＃39; self＆＃39;。我也在使用scapy和我在python 2.7上。
这是一个类似的问题https://i11.at/dwl/eos/kivy30.pdf，但我的错误是
OSError: [Errno 13] Permission denied: '/dev/input/event5'

答案 0 :(得分：0)
在字符串构造的中间有format(self.self.MAC)。这就是为什么你得到关于没有self.self。
输入错误并不重要，它只是来自kivy查询输入设备以查看可用的内容。
