Ruby on rails Gem:：Ext:：BuildError:错误：无法生成Gem本机扩展。-CentOS 6.5

我正在尝试让Ruby版本2.0.0-p353在CentOS 6.5的Nginx 1.4.7上运行。一切都按预期安装，但当我运行

bundle install

时，出现以下错误：

Gem:：Ext:：BuildError:错误：无法生成Gem本机扩展

An error occurred while installing pg (0.17.1), and Bundler cannot continue.
Make sure that `gem install pg -v '0.17.1'` succeeds before bundling.

我找不到提到的mkmf.log文件

checking for libpq-fe.h... no

您需要Postgresql开发库

尝试：

---

或者任何特定于您的操作系统的东西。

您已经准备好安装了

postgersql

？可能与OK重复，所以我尝试了这个方法，认为它解决了问题，但没有。仍然得到完全相同的错误。当我执行

yum安装postgresql-devel

时，我实际上得到了响应

包postgresql93-devel-9.3.4-1PGDG.rhel6.x86\u 64已安装且最新版本

请尝试：

导出路径=/usr/pgsql-9.3/bin:$PATH

捆绑安装

可以确认@SreekanthGS解决方案工作正常。使用

/usr/bin/pgsql-9.3/bin:

预结束我的

$PATH

，然后重新启动我的会话，使gem安装顺利！我确认。我需要这最后一步。

yum install postgresql-devel
