Question

当我从Python shell运行以下行时，代码挂起：

from pymongo import Connection
c = Connection('localhost', 27017)

我想它正等着从mongo服务器回来。当我中断通话时，我得到追溯：

^CTraceback (most recent call last):

KeyboardInterrupt

mongod选择不回应吗？看起来我等待从套接字接收数据。

然而，这有效（这意味着mongod正常运行）：

$ mongo --port 27017
MongoDB shell version: 2.0.1
connecting to: 127.0.0.1:27017/test

Answer 1

抱歉愚蠢的错误。我把mongod的工作停在了后台。

pymongo在创建Connection时挂起
