Question

对于某些共鸣，我似乎无法让Kivy "Hello world"起作用。

我花了几个小时在线研究这个问题并查看了我在Stack Overflow上可以找到的所有相关问题。

我删除并重新安装了kivy和python。

我已经安装了所有kivys依赖项，还有枕头。

如果它有所作为我正在使用python 3。

这是我的代码。

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

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

TestApp().run()

这是我得到的回应。

任何帮助将不胜感激。

Take a look at this answer. It appears you need kivy.deps.sdl2.
