Question

我在Windows 7 64位计算机上安装了Celery 3.1.5，RabbitMQ服务器3.2.1和Python 2.7.5。这是我从first-steps-with-celery复制的代码。

from celery import Celery

app = Celery('tasks', backend='amqp', broker='amqp://guest@localhost//')

@app.task
def add(x, y):
    return x + y

当我从python shell执行任务时，我得到了“操作超时”异常消息。州和ready（）总是返回PENDING＆amp;假

>>> from tasks import *
>>> result = add.delay(4, 4)
>>> result.ready()
False
>>> result.state
'PENDING'
>>> result.get(timeout=20)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\site-packages\celery\result.py", line 136, in get
    interval=interval)
  File "C:\Python27\lib\site-packages\celery\backends\amqp.py", line 154, in wait_for
    raise TimeoutError('The operation timed out.')
celery.exceptions.TimeoutError: The operation timed out.

我验证了RabbitMQ服务器正在运行但是我不知道为什么芹菜抛出异常。
