Answer 1

您缺少 PIL 相关性，请通过

安装

py -3.5 -m pip install pillow

Pillow 是 python3 PIL ......

Answer 2

[CRITICAL] [Window ] Unable to find any valuable Window provider. sdl2 - ImportError: DLL load failed: The specified module could not be found.

来自官方Kivy网站：https://kivy.org/docs/installation/installation-windows.html

安装依赖项（如果不需要，请跳过gstreamer（~120MB），请参阅   Kivy的依赖关系）：

python -m pip install docutils pygments pypiwin32 kivy.deps.sdl2   kivy.deps.glew

python -m pip install kivy.deps.gstreamer

尤其是 kivy.deps.sdl2

kivy第一个程序中的错误如何纠正呢？
