Question

我的问题很简单：在我的覆盆子pi模型上运行'python'命令（不是脚本）A +运行Raspbian Wheezy会出现分段错误：

pi@raspberrypi ~ $ python
Segmentation fault

我在python脚本中发现了很多处理“分段错误”的线程（通常与external C modules相关）。其他一些更具体的关于树莓派的人在apt-get升级期间经常谈到“分段错误”，涉及python模块（here或there）。

但那些人没有回答我的问题。

在gdb中运行它：

pi@raspberrypi ~ $ gdb python

我找到了this related post，但没有给出明确的解决方案。

最后一个元素：python3工作正常。

这里有人会知道发生了什么吗？

感谢您的帮助〜

运行Python时从GDB获取的消息表明您尝试使用的Python可执行文件由于某种原因已损坏。尝试重新安装所有与Python相关的包：

$ sudo apt-get install --reinstall `dpkg --get-selections | grep -E '^(lib)?python' | cut -f1 | cut -d: -f1`
