Raspberry Pi Zero上的Python非法指令 [英] Python Illegal instruction on Raspberry Pi Zero

问题描述

当我尝试运行python脚本时，我得到了Illegal instruction，仅此而已，它没有提供更多详细信息，所以我不知道发生了什么，是否有办法找出导致错误? 另外，我使用sudo运行代码，但没有得到任何输出，程序仅退出.

更新:

我正在运行的脚本是bluez的simple-agent脚本: https://github.com/pauloborges/bluez/blob/master/测试/简单代理

此外，我像 @buratino 这样一行一行地运行，第二行出现了错误:

from gi.repository import GObject

解决方案

像 @Notlikethat 所说，Illegal instruction当正在执行的代码针对其他体系结构进行编译时，Raspberry Pi使用ARM.

也就是说，我发现GObject似乎是引起问题的原因.无论如何，我卸载了已安装的每个与蓝牙相关的软件包，并使用raspbian存储库重新安装了它们，现在Illegal instruction消失了，脚本可以正确执行.

为什么会这样?嗯，我有一个Raspberry Pi Zero，这意味着我没有以太网端口，在我购买WiFi加密狗之前，我先通过下载一些软件包来安装它们.计算机，并将.deb存储在SD卡中，当然，这意味着我必须手动检查我是否下载了正确版本的软件包，我一定把其中一个弄乱了.

经验教训，切勿尝试手动安装软件包，让apt-get完成所有工作！

When I try to run a python script I get Illegal instruction and that's it, it doesn't give any more details so I have no idea what's going on, is there a way to find out what is causing the Illegal instruction error? Also, I run the code using sudo I don't get any output, the program just exits.

UPDATE:

The script I'm running is the simple-agent script from bluez: https://github.com/pauloborges/bluez/blob/master/test/simple-agent

Also, I ran line by line like @buratino said and I got the error in the second line:

from gi.repository import GObject

解决方案

Like @Notlikethat said, the Illegal instruction error happens when the code being executed was compiled for a different architecture, Raspberry Pi uses ARM.

That said, I found out that GObject seemed to be causing the problem. Anyway, I uninstalled every bluetooth related package I had installed and reinstall them using the raspbian repository and now the Illegal instruction is gone and the script executes correctly.

Why did this happen? Well, I have a Raspberry Pi Zero which means I don't have an Ethernet port, before I bought a WiFi dongle I installed a few packages by downloading them on my computer and storing the .deb in the SD card, of course this means I have to manually check that I'm downloading the right version of the package, I must've messed up in one of them.

Lesson learned, never try to manually install packages, let apt-get do all the work!
