请原谅 python 解释器的复制和粘贴，但我正在尝试使用 Kombu，但我似乎无法创建消费者。请帮忙，我在这里完全处于黑暗之中。

>>> from kombu.messaging import Consumer, Producer
>>> from kombu.entity import Exchange, Queue
>>> x = Exchange("stmt",type="topic")
>>> helloQ = Queue("hello", exchange=x, routing_key="stmt.hello")
>>>
>>> from kombu.connection import BrokerConnection
>>> conn = BrokerConnection("scheduledb.lab.compete.com", "clippy", "clippy", "clippy")
>>> channel = conn.channel()
>>> c = Consumer(channel, helloQ)

看看错误

amqplib.client_0_8.exceptions.AMQPConnectionException: (530, u"NOT_ALLOWED - parameters for queue 'hello' in vhost 'clippy' not equivalent", (50, 10), 'Channel.queue_declare')

这意味着队列已经被声明了，但是除了你现在声明的参数之外，还有其他参数。

添加到@asksol 的答案。如果您使用的是 rabbitmq，您可以使用rabbitmqctl命令列出队列详细信息并将这些设置与您自己代码中的设置进行比较。希望这可以为您提供足够的信息来检测冲突。
