【问题描述】：

这是我第一次尝试使用 Kivy，但我一直无法运行基本代码。

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


class TestApp(App):
    def build(self):
        return Button(text='Hello World')


TestApp().run()

我的错误日志如下：

我尝试重新安装 Kivy，安装所有依赖项，但这些结果没有任何改变。有人知道我该如何解决这些问题吗？

【参考方案1】：

看起来像duplicate。

当我没有给主文件main.py命名时，我遇到了这个错误。
