这可以从命令行正常工作，但不能通过网络：
#!/usr/bin/python
# -*- coding: utf-8 -*-
import cgitb
cgitb.enable()
from pymongo import Connection
print "Content-Type: text/html" # HTML is following
print # blank line, end of headers
print "<TITLE>CGI script output</TITLE>"
print "<HTML>Here</HTML>"
connection = Connection()
该文件位于我的 cgi-bin 目录中。当我尝试通过网络运行它时，我得到：
A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred.
