我正在使用 web.py，由于某种原因，我收到以下错误：

[Thu Sep 29 13:47:20 2011] [error] [client 64.8.210.120]   File "/usr/lib/python2.6/site-packages/web.py-0.36-py2.6.egg/web/db.py", line 975, in __init__
[Thu Sep 29 13:47:20 2011] [error] [client 64.8.210.120]     import MySQLdb as db
[Thu Sep 29 13:47:20 2011] [error] [client 64.8.210.120] ImportError: No module named MySQLdb

这是我的 sys.path，万一那是罪魁祸首？不过，我看到了.egg，所以我不知道。想法？

 ['', '/usr/lib/python2.6/site-packages/Bravo-1.7.2-py2.6.egg', 
    '/usr/lib/python2.6/site-packages/Twisted-11.0.0-py2.6-linux-i686.egg',
     '/usr/lib/python2.6/site-packages/construct-2.04-py2.6.egg',
 '/usr/lib/python2.6/site-packages/zope.interface-3.7.0-py2.6-linux-i686.egg', '/usr/lib/python2.6/site-packages/web.py-0.36-py2.6.egg', 
'/usr/lib/python2.6/site-packages/MySQL_python-1.2.3-py2.6-linux-i686.egg', 
    '/usr/lib/python2.6/site-packages/setuptools-0.6c12dev_r88846-py2.6.egg',
     '/usr/lib/python26.zip', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', 
    '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/lib/python2.6/site-packages',
     '/usr/lib/python2.6/site-packages/PIL']

以下是 2.6 site-packages 目录的内容：

[root@xxxx ~]# locate *.egg
/root/MySQL-python-1.2.3/dist/MySQL_python-1.2.3-py2.6-linux-i686.egg
/usr/lib/python2.4/site-packages/errorhandler-1.1.1-py2.4.egg
/usr/lib/python2.4/site-packages/setuptools-0.6c11-py2.4.egg
/usr/lib/python2.4/site-packages/xlrd-0.7.1-py2.4.egg
/usr/lib/python2.4/site-packages/xlutils-1.4.1-py2.4.egg
/usr/lib/python2.4/site-packages/xlutils-1.4.1-py2.5.egg
/usr/lib/python2.4/site-packages/xlwt-0.7.2-py2.4.egg
/usr/lib/python2.6/site-packages/Bravo-1.7.2-py2.6.egg
/usr/lib/python2.6/site-packages/MySQL_python-1.2.3-py2.6-linux-i686.egg
/usr/lib/python2.6/site-packages/Twisted-11.0.0-py2.6-linux-i686.egg
/usr/lib/python2.6/site-packages/construct-2.04-py2.6.egg
/usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg
/usr/lib/python2.6/site-packages/setuptools-0.6c12dev_r88846-py2.6.egg
/usr/lib/python2.6/site-packages/web.py-0.36-py2.6.egg
/usr/lib/python2.6/site-packages/zope.interface-3.7.0-py2.6-linux-i686.egg

如果我打开 python（2.4 或 2.6），我可以import MySQLdb毫无问题。

谢谢，汤姆

在你的 bashrc（通常在/etc/bashrc）文件的底部放这个（或者只是更新PYTHONPATHenv 变量以包含/usr/lib/python2.6/site-packages）：

if [ $PYTHONPATH ]
then
    export PYTHONPATH=$PYTHONPATH:/usr/lib/python2.6/:/usr/lib/python2.6/site-packages/
else
    export PYTHONPATH=/usr/lib/python2.6/:/usr/lib/python2.6/site-packages/
fi

或者，对于运行脚本的特定用户，将上述内容放入/home/[USER_RUNNING_SCRIPT]/.bashrc.

然后源文件：

$ source ~/.bashrc
# or
# source /etc/bashrc

尝试编写一个简单的页面来显示 sys.path，因为它存在于 Web 服务器执行环境中。不确定这是否是您在问题中显示 sys.path 时显示的内容，或者您​​是否从登录名中以交互方式运行该内容。运行 http 服务器的用户 ID 可能与您作为普通用户所拥有的环境设置不同。
