Question

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计算机上运行良好。然而，在Raspbian上，它崩溃了一个奇怪的错误链接到Kivy自己的一个函数。

这里是终端输出：

就像一个疯狂的猜测，看看它是如何工作的，我试着编辑Kivy＆＃34; create_window（）＆＃34;函数，位于＆＃34; /usr/local/lib/python2.7/dist-packages/kivy/core/window/window_egl_rpi.py"中，通过在其声明中添加可选参数。再次运行我的程序产生了某种分段错误，所以我不再搞乱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）

我遇到了同样的错误，同样的情况 - 我的程序在Windows机器上运行良好，但在RPi上崩溃时出现相同的错误。就我而言，我正在运行更新的Python版本--2.7.9。

Window.size 分配似乎是崩溃的来源：

class MainApp(App):
  def build(self):
    Window.size = (1280,800)     # <---- Crashes on RPi

删除此作业修复了该程序。
