我正在使用virtualenv,我需要安装"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:

我正在尝试使用psycopg2与sslmode ='required'参数连接到我的postgres数据库; 但是,我收到以下错误

psycopg2.OperationalError: sslmode value "require" invalid when SSL support is not compiled in

这是关于我的系统的几个细节

• Mac OS X El Capitan
• Python 2.7
• 通过pip安装psycopg2
• 通过自制软件安装python

这是我试图解决问题的方法

• brew uninstall python
• which python仍然显示python生活在/usr/local/bin/python,试图卸载这个但不能.并且听说这是操作系统使用的python,不管怎么说都不应该卸载
• brew install python --with-brewed-openssl --build-from-source
• pip uninstall psycopg2
• pip install psycopg2

完成所有这些后,异常仍然发生.我通过运行这个python脚本#!/usr/bin/env python不知道它的问题,但是这是一个不同的目录比一个which python节目
