推荐答案

该错误通常是由于您的计算机的图形芯片非常差，或者显卡驱动程序差.您的卡和驱动程序必须支持 OpenGL ES 2 才能使 Kivy 应用程序正常工作.如果您在虚拟机中运行它，请确保您已为该虚拟机打开 3D 加速.

That error is usually due to your computer having a very poor graphics chip, or poor video card drivers. Your card and drivers must support OpenGL ES 2 for Kivy apps to work. If you are running this in a virtual machine, make sure you have turned on 3D acceleration for that VM.
