Question

我刚刚开始我的第一个kivy项目。我想知道如何调试这种东西。即使我深入调试了kivy代码，我也不知道哪种属性错误或缺失。因此，我不仅要求解决这个问题，还要求有效分析问题的想法。这是python和kivy-lang代码以及运行时日志记录。

的Python：

from kivy.uix.boxlayout import BoxLayout
from kivy.uix.gridlayout import GridLayout
from kivy.app import App

class MainLayout(BoxLayout):
    pass

class MenuLayout(GridLayout):
    pass

class HomeToucherApp(App):
    def build(self):
        return MainLayout()

if __name__ == "__main__":
    HomeToucherApp().run()

KV-郎：

<MainLayout>:
    orientation: 'vertical'
    padding: 20
    spacing: 10
    Button:
        text: "Screen"
        size_hint: 1, 1
    MenuLayout:
        cols: 2
        size_hint: 1, 0.1
        Button:
            text: "Edit"
        Button:
            text: "Setup"

日志：
