Kivy 窗口不显示。我已经重新安装了数百次。

安慰：

我正在学习 kivy，我想从 kivymd 制作一组可滚动的按钮，为此我使用 MDScrollViewRefreshLayout（取自示例）。但是有些按钮是不可见的，可见的不滚动。我想看看使用 ScrollView 的最简单的例子，这样 python 代码和标记是分开的。我找到了一个对我来说很清楚的示例，但是没有单独的标记文件，我无法弄清楚如何获得所需的结果。

在此处输入图像描述

主文件

from kivy.factory import Factory

from kivymd.app import MDApp
from kivy.lang import Builder
from kivy.config import Config
from kivy.core.window import Window

Config.set('graphics', 'resizable', '0')    
Window.size = (351, 512)                     

Builder.load_file('dictionary.kv')

class Basic(MDApp):
    def __init__(self, **kvargs):
        super(Basic, self).__init__(**kvargs)
        self.main = Factory.MainMenu()

    def build(self):
        return self.main

Basic().run()

字典.kv：

是的，我刚开始研究这个话题，所以不要严格判断：D

所以为了测试我铆了最简单的东西

主要.py：

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

class Interface():
    pass

class MyApp(App):
    def build(self):
        return Interface()

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

我的应用程序.kv

#:kivy 1.10.1
<Interface>:
    BoxLayout:
        orientation:vertical
        Button:
            text:Hello

解释器返回什么

     raise Exception('Invalid instance in App.root')

怎么做，怎么做？）
