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

Question

这个错误似乎是常见的Windows盒，但我的Linux亚马逊EC2实例抛出这个错误，当我npm install pg：

../src/binding.cc:1:23: fatal error: pg_config.h: No such file or directory 
#include <pg_config.h> 
        ^
compilation terminated. 
make: *** [Release/obj.target/binding/src/binding.o] Error 1

我在亚马逊的Linux 2014.03，这是一个微运行实例节点0.10.28。

Postgres 9.2.7从Amazon回购站安装。具体来说就是postgresql9*包。

在新鲜updatedb，locate pg_config回报

/usr/bin/pg_config 
/usr/share/locale/cs/LC_MESSAGES/pg_config-9.2.mo 
/usr/share/locale/de/LC_MESSAGES/pg_config-9.2.mo 
/usr/share/locale/es/LC_MESSAGES/pg_config-9.2.mo

/usr/share/locale/zh_TW/LC_MESSAGES/pg_config-9.2.mo 
/usr/share/man/man1/pg_config.1.gz 

但locate pg_config.h回报什么。

任何想法？

Answer 1

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

node-postgres需要的头文件位于缺少的开发包中。下面的步骤固定我的问题：

1. 删除node-postgres目录：

   $ rm -rf node_modules/pg

2. 安装从回购Postgres的开发包（精心搭配您的版本 - 亚马逊回购是一个烂摊子当涉及到postgres）：

   $ sudo yum install postgresql9-devel

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

   $ npm install pg

的pg_config.h文件应该有，所以安装应该正常工作！
