在eclipse上无法从python连接到mongodb

Question

我第一次尝试使用mongodb和python（使用eclipse）

import pymongo
connection = pymongo.Connection("localhost",27017)
db=connection.test
db.name

出现此错误：

Traceback (most recent call last):
 File "C:\Users\chatterjees\workspace\de.vogella.python.first\src\FirstModule.py", line      2, in <module>
    connection = pymongo.Connection("localhost",27017)
