在Amazon Linux上安装node-postgres出错.缺少pg_config.h文件

Question

这个错误似乎在windows盒子上很常见，但我的Amazon Linux EC2实例在我npm install pg:

时抛出这个错误:

../src/binding.cc:1:23: fatal error: pg_config.h: No such file or directory
 #include <pg_config.h>
                       ^
compilation terminated.

我在Amazon Linux 2014.03上，它是一个运行节点0.10.28的微实例。

Postgres 9.2.7是从Amazon repos安装的。具体来说，是postgresql9*包。

在新的updatedb上，locate pg_config返回

/usr/bin/pg_config

/usr/share/man/man1/pg_config.1.gz

但是locate pg_config.h什么也没有返回。

任何想法?

默认安装postgresql9、postgresql9-libs和postgresql9-server，但不安装postgresql9-devel。

node-postgres所需的头文件在缺失的开发包中。下面的步骤修复了我的问题:

1. 删除node-postgres目录:

   $ rm -rf node_modules/pg

2. 从repos安装postgres开发包(仔细匹配您的版本- Amazon repos在postgres方面是一团糟):

   $ sudo yum install postgresql9-devel

3. 重新安装node-postgres(我在本地做，你可能正在使用-g选项):

   $ npm install pg

pg_config.h文件应该在那里，所以安装应该可以正常工作!
