Kivy 시작하기

Question

'pyforms'시도가 실패한 후 'kivy'로 손을 사용하기로 결정했습니다.

그냥 this example code를 실행하려고 pip install kivy

통해 설치하지만 난이 오류가 발생합니다. 나는 그것이 무엇을 말하려고하는지 정말로 이해하지 못하기 때문에 이것을 어디에서 시작해야할지 모른다. 32 비트 Python3.4.4를 실행하는 Windows 10입니다. 다른 사람이 오류를 이해할 수 있습니까?

TestApp().run()

Kivy 사이트에서 installation guide을 따르십시오. 다음과 같은 종속성도 설치해야합니다.

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