我最近按照Kivy网站上的说明在Raspberry Pi（使用Raspbian系统）上安装了Kivy。
我打算测试我写的程序。它在我的Linux Mint计算机上工作正常。然而，在Raspbian上，它崩溃了一个奇怪的错误，链接到Kivy自己的功能之一。
这是终端输出：

作为一个疯狂的猜测，为了看看它将如何工作，我试图编辑Kivy的"create_window（）"函数，位于"/usr/local/lib/python2.7/dist-packages/kivy/core/window/window_egl_rpi.py"中，方法是在其声明中添加一个可选参数。再次运行我的程序会产生某种分割错误，所以我停止弄乱 Kivy 的代码......
知道如何修复此日志中提示的错误吗？（MainApp（）.run（） 是我程序的最开始，其他一切都是 Kivy 函数，显然是由这个命令自动调用的）
我在相同的场景中遇到了相同的错误 - 我的程序在 Windows 机器上运行良好，但在 RPi 上崩溃并出现相同的错误。就我而言，我正在运行更新的 Python 版本 - 2.7.9。
看来 Window.size 赋值是崩溃的根源：
class MainApp(App):
def build(self):
Window.size = (1280,800) # <---- Crashes on RPi
删除此分配修复了程序。
