我对 node.js 非常（非常）新，在服务器端配置和编码方面也相当绿色。（我有很长的客户端编程历史，最近使用的是 Adobe Flex 和 ActionScript。）
无论如何，我让 Rackspace（为我管理 Linux 服务器）安装 node.js 和 node-postgres。
从票证中的评论来看，安装过程是这样的：

Installing : nodejs-stable-release [1/1]
Installed: nodejs-stable-release.noarch 0:5-3
Complete!

一个小小的“Hello world” node.js 示例运行良好（万岁！），但是一个简单的 Postgres 示例在require('pg')声明中失败，说找不到模块。我查看了服务器，在任何地方都找不到pg.js文件。
关于为什么 node-postgres 构建失败的任何线索？
