如何使用Node.js模块？

Question

我最近在一个新的Linode盒子上安装了Node.js，我想我处于一个奇怪的情况，我不能使用require()加载任何第三方模块。

我已经安装npm并通过npm已成功安装模块，但每当我试图模块require一个（或只在同一目录下的一些我自己的代码），Node.js的throws的error说它找不到该模块。

有关为什么会发生这种情况的任何想法？

下面是一个例子错误消息：

root@li200-141:/home/mike# npm install sequelize 
npm ERR! sudon't! 
npm ERR! sudon't! Running npm as root is not recommended! 
npm ERR! sudon't! Seriously, don't do this! 
npm ERR! sudon't! 
npm info it worked if it ends with ok 
npm info version 0.2.2 
npm info fetch http://registry.npmjs.org/sequelize/-/sequelize@0.4.2.tgz 
npm info install sequelize@0.4.2 
npm info activate sequelize@0.4.2 
npm info build Success: sequelize@0.4.2 
npm ok 

root@li200-141:/home/mike# node

显然，存在节点v0.2.2，防止从REPL正常工作需要的错误。

尝试将代码放在.js文件中。这对我有效。
