web.py不導入MySQLdb

Question

我正在使用web.py，由於某種原因，出現以下錯誤：

[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

這是我的sys.path，以防萬一。 我看到the.egg，但是我不知道。 有什么想法嗎？

 ['', '/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目錄的內容：

[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

如果我打開python（2.4或2.6），則可以import MySQLdb 。

謝謝湯姆

Answer 1

在您的bashrc文件的底部（通常在/etc/bashrc文件中）將此文件放置（或僅更新PYTHONPATH env變量以包含/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，對於正在運行腳本的特定用戶，將以上內容放在/home/[USER_RUNNING_SCRIPT]/.bashrc 。

然后獲取文件：

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

您可以在以下位置下載mysqldb： http ： //sourceforge.net/projects/mysql-python/

嘗試編寫一個簡單的頁面，以顯示sys.path在Web服務器執行環境中是否存在。 不知道這是您在問題中顯示sys.path還是從登錄名以交互方式運行時所顯示的內容。 可能是http服務器所運行的userid與常規用戶所設置的環境不同。
