我正在尝试在 Mac OS X 上安装猫鼬：

$ sudo npm install -g mongoose
npm http GET https://registry.npmjs.org/mongoose
npm http 304 https://registry.npmjs.org/mongoose
npm http GET https://registry.npmjs.org/hooks/0.2.1
npm http GET https://registry.npmjs.org/mongodb/1.1.11
npm http GET https://registry.npmjs.org/ms/0.1.0
npm http GET https://registry.npmjs.org/sliced/0.0.3
npm http 304 https://registry.npmjs.org/hooks/0.2.1
npm http 304 https://registry.npmjs.org/mongodb/1.1.11
npm http 304 https://registry.npmjs.org/ms/0.1.0
npm http 304 https://registry.npmjs.org/sliced/0.0.3
npm http GET https://registry.npmjs.org/bson/0.1.5
npm http 304 https://registry.npmjs.org/bson/0.1.5

> bson@0.1.5 install /usr/local/lib/node_modules/mongoose/node_modules/mongodb/node_modules/bson
> node install.js || (exit 0)

不应该require工作吗？难道我做错了什么？

根据npm 常见问题解答：

我在全球范围内安装了一些东西，但我不能 require() 它

在本地安装它。

全局安装位置是命令行实用程序将其 bin 放入系统的位置PATH。它不适用于require().

如果您require()的代码中有一个模块，那么这意味着它是一个依赖项，并且是您程序的一部分。您需要在程序中本地安装它。
