from kivy.app import App

class MyApp(App):
    pass

if __name__ == "__name__":
    Myapp().run()

哪里有问题?

答案 0 :(得分:1)

由于您未在build()方法中返回root,因此应用程序无法启动,因此kivy不会加载更多组件,因此应用程序将关闭。

<强>解决方案:

返回一个小部件。

from kivy.app import App
from kivy.uix.button import Button

class TestApp(App):
    def build(self):
        return Button(text='hello world')

if __name__ == '__main__':
    TestApp().run()
