将模块添加到pythonpath - 没有任何作用

Question

我没有root访问权限所以我将psycopg2模块安装到/ opt(我有权访问该目录):

$python setup.py install --prefix=/opt

我尝试了几种方法:

#.bashrc        
PATH=$PATH:$HOME/bin:/opt/lib/python2.4/site-packages/psycopg2/
export PATH  

要么

#.bash_profile  
PATH=$PATH:$HOME/bin:/opt/lib/python2.4/site-packages/
export PATH

我也试过了 sys.path.append('/opt/lib/python2.4/site-packages/psycopg2/')

没有用:

$python  
>>>import psycopg2
>>>no psycopg2 module

两者都没有/opt/lib/python2.4/site-packages/psycopg2/或/opt/lib/python2.4/site-packages/路径有效

请帮忙,谢谢

尝试$PYTHONPATH而不是$PATH在bash配置文件中.有关更多信息,请查看有关此主题的官方文档.
