为node.js安装node-postgres模块时,构建失败

标签: postgresql node.js install

我对node.js非常(非常)新手,在服务器端配置和编码方面也非常环保。 (我有很长的客户端编程历史,最近有Adobe Flex和ActionScript。)

无论如何,我问Rackspace(谁为我管理Linux服务器)安装node.js和node-postgres。

根据故障单中的评论,该安装是这样的:


的node.js

Complete!

一个小的“Hello world”node.js示例工作正常(万岁!),但是一个简单的Postgres示例在require('pg')语句上失败,说无法找到该模块。我查看了服务器,无法在任何地方找到pg.js文件。

有关为什么node-postgres构建失败的任何线索?

全局安装:

npm install -g pg

您可能需要成为root用户,例如与

sudo npm install -g pg
