Question

安装Kivy后，我尝试运行Hello World应用程序，但是出现错误。我已经google了，但找不到满意的答案。这是错误：

Answer 1

该错误通常是由于您的计算机具有非常差的图形芯片或不良的视频卡驱动程序。您的卡和驱动程序必须支持OpenGL ES 2才能使用Kivy应用程序。如果您在虚拟机中运行此操作，请确保已为该VM启用了3D加速。

我在kivy的virtualenv安装（直接从GitHub安装）中收到了同样的错误消息（＆＃34;无法获取窗口，中止。＆＃34;），如下所示：

pip install hg+http://bitbucket.org/pygame/pygame
pip install Cython
pip install git+git://github.com/kivy/kivy.git

在我的情况下，有一个与png有关的先前错误，所以我尝试在我的virtualenv中安装枕头：

pip install pillow

它现在正在运作。
