推荐答案

该错误通常是由于计算机的图形芯片性能很差或视频卡驱动程序性能很差.您的卡和驱动程序必须支持OpenGL ES 2，Kivy应用程序才能运行.如果您在虚拟机中运行此程序，请确保已为该VM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.
