Kivy hello world不工作

Question

我正在尝试让kivy在我的Ubuntu系统上工作。我遵循了他们wesbite中的说明。

但是当我试图从他们的网站上运行下面的hello world代码时：

import kivy
kivy.require('1.5.1') # replace with your current kivy version !

from kivy.app import App
from kivy.uix.button import Button

class MyApp(App):
    def build(self):
        return Button(text='Hello World')

if __name__ == '__main__':
    MyApp().run()

我得到以下错误：

[INFO   ] Kivy v1.5.1

是不是和我的显卡有关？我使用的是ATI Mobility Radeon HD 5400显卡。

最终通过将Ubuntu更新到12.10来让它工作，似乎问题出在图形驱动程序上。现在，示例的运行情况与预期一致。谢谢琼杰和夸诺。

我按照你提供的指示去做。使用你提供的代码，我得到了这个结果。如图所示

。python版本是python2.7。我使用的系统是ubuntu12.10。

代码需要超级用户权限，我从命令行运行代码: sudo python demo.py

尝试使用'sudo‘来运行它。
