python - 树莓派上的“python”命令段错误

Question

我的问题相当简单:在运行 Raspbian Wheezy 的树莓派型号 A+ 上运行“python”命令(不是脚本)会出现段错误:

pi@raspberrypi ~ $ python
Segmentation fault

我发现相当多的线程在 python 脚本中处理“段错误”(通常与 external C modules 相关)。其他一些更具体地讨论树莓派的人经常谈到 apt-get 升级期间的“段错误”，涉及 python 模块( here 或 there )。

但这些并不能解决我的问题。

在 gdb 中运行它给出:

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 工作得很好。

这里有人知道发生了什么吗？

谢谢你的帮助~

运行 Python 时从 GDB 收到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Python相关的包:

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