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:

Virtualenv非常棒:它让我可以保留许多不同的Python安装,这样不同项目的依赖关系就不会全部集中在一起.

但是,如果我想在Windows上安装一个打包为.exe安装程序的软件包,我如何指导它安装到virtualenv？例如,我有pycuda-0.94rc.win32-py2.6.exe.当我运行它时,它会检查注册表,并且只找到一个要安装的Python26,这是我的virtualenv所基于的常见的.

如何指导它安装到virtualenv？

我在virtualenv中安装了psycopg2 easy_install psycopg2.我没有看到任何错误,看起来安装很顺利..有一个鸡蛋文件在site-packages目录中为psycopg2创建..

但是当我在解释器中运行import psycopg2时,我得到了以下错误..任何线索？我该如何解决..在virtualenv中安装psycopg2的任何其他方法..

Traceback (most recent call last):

谢谢.
