在我的RaspberryPi上我使用的是Python v3.4.3。
最近，我（有点成功）通过以下shell命令设法安装了Kivy v1.9.1-dev：
sudo echo "deb http://vontaene.de/raspbian-updates/ . main" > /etc/apt/sources.list.d/gstreamer.list
sudo apt-get install pkg-config libgl1-mesa-dev libgles2-mesa-dev python-pygame python-setuptools libgstreamer1.0-dev git-core gstreamer1.0-plugins-{bad,base,good,ugly} gstreamer1.0-{omx,alsa} python-dev
sudo pip3.4 install cython
...
cd ~
git clone https://github.com/kivy/kivy
cd kivy
python3.4 setup.py build
sudo python3.4 setup.py install
安装花了相当长的时间，但最后，我觉得它进展顺利。
我将Pi更改为桌面模式（startx），打开一个shell，当我尝试启动示例＆＃34; shader＆＃34;时，我得到以下输出：

有人看到我做错了什么，或者有人帮我找到让Kivy在我的Pi上运行的方法吗？
