编辑
确定我发现这个哪种告诉我出了什么问题。现在，当我从\home进入 python ，我执行 import psycopg2 它不会给我任何ImportError但是当我在虚拟环境中时，我得到ImportError
Ok I found this link which kind of tells me what went wrong. Now when i get into the python from \home, and i execute import psycopg2 it does not give me any ImportError but when i am inside the virtual env, I get the ImportError
(django-env)smaranh@ubuntu:~/geodjango$ python
Python 2.7.2+ (default, Oct 4 2011, 20:06:09)
[GCC 4.6.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import psycopg2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named psycopg2
现在链接指导我如何附加路径但是，由于我是新的，我并不真正理解这个过程，我不希望进一步弄清楚。所以有人可以一步一步地指导我如何附加 sys.path ??
Now the link guides me in how to append the path but i am not really understanding the process since I am new and i do not wish to screw it up further. So can somebody pls guide me step by step how to append the sys.path??
推荐答案
如果您使用的是virtualenv，则需要在环境中安装psycopg2，例如：
If you are using virtualenv you need install psycopg2 inside the environment, something like:
pip install psycopg2
但是您需要在之前安装一些apt：
but you need install some packages with apt before that:
sudo apt-get install python-dev postgresql-server-dev-all
