Raspberry Pi ARM的Mongodb MongoClient.connect()上的总线错误

问题描述

我已尝试在x64计算机上执行此节点脚本，并且看起来工作正常.

I have tried executing this node script on an x64 computer, and it appears to work fine.

但是，相同的脚本在Raspberry Pi上运行时报告总线错误.它给出[6047.715610]未处理的错误:对齐异常错误，并在下一行报告此错误，作为总线错误.看来该错误源于MongoClient.connect().

However, the same script reports a bus error when run on the Raspberry Pi. It gives a [6047.715610] Unhandled Fault: alignment exception error, with the error reported on the next line, as a Bus error. It appears that the error stems from MongoClient.connect().

该脚本利用了mongodb模块中的MongoClient和GridStore.另外，我尝试从此存储库重新安装(似乎执行gyp-rebuild)，但失败.

The script utilizes MongoClient and GridStore from the mongodb module. In addition, I have attempted a re-installation from this repository (which appears to do a gyp-rebuild), and it fails.

是否应该设置任何编译选项?

Is there any compilation option that should be set?

推荐答案

我设法通过从github中提取存储库，编辑bson.h并对其执行node-gyp rebuild来解决该错误.

I managed to fix the error by pulling the repo from github, editing bson.h, and doing a node-gyp rebuild on it.

显然，该错误是由ARM设备不支持的编译选项引起的. 以防万一有人感兴趣:

Apparently, the error is caused by a compilation option which is not supported by ARM devices. Just in case anyone is interested:

1. 此处的Git克隆存储库:https://github.com/mongodb/node-mongodb-native
2. 打开./node-mongodb-native/node_modules/bson/ext/bson.h
3. 将#define USE_MISALIGNED_MEMORY_ACCESS从1更改为0
4. 执行node-gyp rebuild重新编译库.

1. Git clone repository here: https://github.com/mongodb/node-mongodb-native
2. Open ./node-mongodb-native/node_modules/bson/ext/bson.h
3. Change #define USE_MISALIGNED_MEMORY_ACCESS from 1 to 0
4. do a node-gyp rebuild to recompile the library.

这对我有用.
