如何修复 Kivy 问题 Sdl2 -import 错误？ （已经尝试过pip'ing）

Question

这是我从kivy website直接复制来测试库的代码。

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

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

TestApp().run()

我收到这个错误

我尝试按照sdl2 中所述卸载并重新安装 - ImportError: DLL load failed: The specified module could not be found and [CRITICAL] [App] Unable to get a Window, abort post

我还尝试关注今年制作的视频，以防我犯了一些错误，但这并没有帮助。

因此，以防万一，其他人有这个问题，我只是在 pycharm 中制作它，然后直接从 CMD 运行它。 不知道为什么会这样，但即使是开发人员也无法弄清楚
