您可能缺少一些依赖项。从文档：
安装依赖项（如果不需要，请跳过gstreamer（〜120MB），请参阅Kivy的依赖项）：
python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2kivy.deps.glew;
python -m pip install kivy.deps.gstreamer
要安装这些依赖项，请打开一个终端（可以是控制台，Pycharm终端窗口等），运行第一个命令，然后运行第二个命令。
解决方法我一直收到此错误：无法找到任何有价值的Window提供程序。带有kivy继承人的“完整”错误：

多数民众赞成在错误和继承人的代码：
import kivy #added this just in casefrom kivy.app import Appfrom kivy.uix.label import Labelclass SimpleKivy(App): def build(self): return Label(text='Hello World!!!')if __name__ == '__main__': SimpleKivy().run()
有人可以解释这个错误
