node.js - npm install --save loopback-connector-mongodb 失败

Question

我是 node.js 的新手，我想学习环回。我尝试按照本教程进行操作，第一部分进展顺利，直到我安装了环回连接器到 mongodb。

npm install --save loopback-connector-mongodb

我遇到了错误，这似乎很难在网上找到，而且我对 npm、node-gyp 和 mongodb 的了解真的很差，所以我什至不知道哪里出了问题。谁能建议如何修复它？

这是终端日志:

npm WARN package.json loopback-getting-started@1.0.0 No license field.

我有 node 版本 4.0.0，ubuntu mate 15.04 和 mongo 3.0.6

错误消息 /usr/bin/ld: cannot find -lkrb5 表示找不到构建 kerberos 模块所需的库 libkrb5。只需安装该库:apt-get install libkrb5-dev 即可消除该错误消息。参见 installation guide .

但是 mongodb 驱动程序没有它也能正常运行，只是不支持 kerberos 身份验证。
