（抱歉，如果这是一个非常简单的问题解决 - 这是我第一个django项目）

解决方案

首先要做的是安装依赖项。

  sudo apt-get build-dep python-psycopg2 
  

之后进入你的virtualenv并使用

  pip install psycopg2 
  

这两个命令应该可以解决问题。

I am trying to set up a PostgreSQL database for my django project, which I believe I have done now thanks to the replies to my last question Problems setting up a postgreSQL database for a django project.

Error: No module named psycopg2.extensions

I'm not sure what this means - I have tried to download psycopg2 but can't seem to find a way to download psycopg2 using homebrew. I have tried easy_install, pip install and sudo but all return errors like this...

Downloading http://www.psycopg.org/psycopg/tarballs/PSYCOPG-2-4/psycopg2-2.4.5.tar.gz

Any help on how to fix this would be very much appreciated!

Thanks

(Sorry if this is a really simple problem to solve - this is my first django project)

解决方案

The first thing to do is to install the dependencies.

sudo apt-get build-dep python-psycopg2

After that go inside your virtualenv and use

pip install psycopg2 

These two commands should solve the problem.
