Mac OS安装psycopg2

系统Mac OS X10.9.4 

如果直接安装

sudo python set.py install 

则可能出现类似如下的错误

Error: pg_config executable not found.Please add the directory containing pg_config to the PATHor specify the full executable path with the option: python setup.py build_ext --pg-config /path/to/pg_config build ...or with the pg_config option in 'setup.cfg'.

解决方法

在setup.cfg中将pg_config参数赋值，值是系统路径下的pg_config

以我的为例，pg_config文件在/Library/PostgreSQL/9.3/bin/pg_config，则在setup.cfg中设置如下

pg_config=/Library/PostgreSQL/9.3/bin/pg_config

然后就可以重新安装了，sudo python set.py install
