创建连接时 pymongo 挂起

Question

当我从 Python shell 运行以下几行时，代码挂起：

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

我猜它正在等待来自 mongo 服务器的回复。当我中断呼叫时，我得到回溯：

^CTraceback (most recent call last):

KeyboardInterrupt

mongod 选择不响应吗？看来我一直在等待从套接字接收数据。

然而，这是有效的（这意味着 mongod 运行正常）：

$ 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。我在后台停止了 mongod 工作。
