python - Python Kivy 错误：[CRITICAL] [App] 无法获取窗口，中止

问题描述

我正在尝试在 Kivy 中运行一些简单的代码。有人可以帮忙吗？注意：我的 PC 上安装了两个硬盘驱动器，我不确定这是否会对路径产生影响。我是新来的。请怜悯我！非常感谢你。

这是我试图运行的代码：

import kivy
from kivy.app import App
from kivy.uix.label import Label


class SimpleKivy(App):
    def build(self):
        return Label(text="Hello World!")

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

这是我收到的错误：
