Question

我有一些python 2.7代码使用Kivy安装并在Raspberry Pi上完美运行但它在BeagleBone Black Rev C上崩溃。代码导入：

from kivy import app
from kivy import clock
from kivy.uix import anchorlayout
from kivy.uix import label
from kivy.core import window

我在Debian Jessie的BeagleBone Black Rev C上运行python 2.7。 Kivy版本1.9.1。这是错误：

编辑：进步！我需要安装Cython。一旦我这样做，我就会遇到以下错误：

[ERROR ] [Window ] Unable to use pygame 
[ERROR ] [Window ] The module raised an important error: 'OpenGL not available'

在Debian上安装Kivy软件包的最简单方法是添加Kivy存储库。

详细说明可在此处找到：https://kivy.org/docs/installation/installation-linux.html

实际上，归结为将以下行添加到/etc/apt/sources.list：

deb http://ppa.launchpad.net/kivy-team/kivy/ubuntu trusty main

然后在以下位置运行此命令：

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A863D2D6

之后你可以安装Kivy：

sudo apt-get install python-kivy

在BeagleBone上使用Python包Kivy的麻烦
