when I try to run this script on my shared server
当我尝试在我的共享服务器上运行这个脚本时
#!/usr/bin/python
import sys, os
sys.path.insert(0, "/home/<username>/python/django")
sys.path.insert(0, "/home/<username>/python/django/www") # projects directory
os.chdir("/home/<username>/python/django/www/<project>")
os.environ['DJANGO_SETTINGS_MODULE'] = "<project>.settings"
from django.core.servers.fastcgi import runfastcgi
runfastcgi(method="threaded", daemonize="false")
But, my web host just installed MySQLdbfor me a few hours ago. When I run python from the shell I can import MySQLdbjust fine. Why would this script report that it can't find it?
但是，我的网络主机MySQLdb几个小时前才为我安装。当我从 shell 运行 python 时，我可以MySQLdb很好地导入。为什么这个脚本会报告找不到它？

You are missing the python-mysql db driver on your python path. see if you can figure out the pythonpath WSGI is seeing... which can be different from what you are experiencing in shell
您的 python 路径上缺少 python-mysql db 驱动程序。看看你是否能找出 WSGI 看到的 pythonpath ......这可能与你在 shell 中遇到的不同

Is it possible that you have the wrong DATABASE_ENGINE setting in your settings.py? It should be mysql and not mysqldb there.
您的 settings.py 中是否有错误的 DATABASE_ENGINE 设置？它应该是 mysql 而不是 mysqldb 那里。
