如何在Python上用“pip”安裝psycopg2？

我正在使用virtualenv，我需要安裝“psycopg2”。

我做了以下事情：pip?install?http://pypi.python.org/packages/source/p/psycopg2/psycopg2-2.4.tar.gz#md5=24f4368e2cfdc1a2b03282ddda814160

我有以下消息：Downloading/unpacking?http://pypi.python.org/packages/source/p/psycopg2/psycopg2-2.4.tar.gz#md5=24f4368e2cfdc1a2b03282ddda814160
