python-3.x - Kivy 2.0 安装难点

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：

我试过重新安装 Kivy，安装所有依赖项，没有任何改变这些结果。有谁知道我该如何解决这些问题？

解决方案

看起来像重复的。

当我没有给出主文件main.py名时，我遇到了这个错误。
