我正在使用virtualenv
并且需要安装“psycopg2”。
我已经做了以下工作:
pip install http://pypi.python.org/packages/source/p/psycopg2/psycopg2-2.4.tar.gz#md5=24f4368e2cfdc1a2b03282ddda814160
我有以下信息:

我的问题是,我只需要这样做就可以让心理医生工作?
python setup.py build_ext --pg-config /path/to/pg_config build ...
在使用Postgres.app版本9.3.2.0rc2的Mac Mavericks上,在安装Postgres之后,我需要使用以下代码:
sudo PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.3/bin pip install psycopg2
在CentOS上,您需要postgres开发包:
这至少是CentOS 6的解决方案。
您需要同时安装PostgresSQL和Python开发包,否则psycopg2安装将失败。
为下面提到的操作系统运行命令,然后再次尝试安装psycopg2。
操作系统/发行版
Debian/Ubuntu公司
Python2
Python3
CentOS 6号
见Banjer's answer
如果这还不够,试试
或者
在再次安装psycopg2之前。
