My problem was that pg_configwas not in the PATH. So, I first needed to search for pg_config's path by using
我的问题是pg_config不在 PATH 中。所以，我首先需要pg_config使用
yum provides "*/pg_config"
After noting the path, I used this command to install pg gem
记下路径后，我使用此命令安装 pg gem
gem install pg -- --with-pg-config=/usr/pgsql-9.4/bin/pg_config
That installed pgsuccessfully. The system was a CentOS.
那安装pg成功了。该系统是一个 CentOS。

pg_configcomes with the development files for PostgreSQL. Go to where you got the server daemon from and look for them there.
pg_config附带 PostgreSQL 的开发文件。转到您从哪里获得服务器守护程序并在那里寻找它们。

later you need install the rigth vertion, for your architecture(32bit or 64bit), in my case was:
稍后您需要为您的架构（32 位或 64 位）安装 rigth 版本，在我的情况下是：
yum install postgresql84-devel-8.4.20-1.el5_10.x86_64
then update
然后更新
yum update
and finally install psycopg2 with pip
最后用pip安装psycopg2
pip install psycopg2
pip 安装 psycopg2
