标签： python celery

我试图在他们的网站（http://docs.celeryproject.org/en/latest/getting-started/first-steps-with-celery.html）上运行celery的入门代码，并且我在后台运行RabbitMQ服务器的实例。但是，我收到了很长的错误消息：

>>> from celery import Celery
>>> app = Celery('tasks', broker='pyamqp://guest@localhost//')
>>> @app.task
... def add(x, y):
...     return x + y
...
>>>
>>> add.delay(4, 4)

在github上存在一个未解决的问题：

https://github.com/celery/py-amqp/issues/130

有人在评论中建议通过将amqp的版本降级为2.1.3暂时解决

要降级的步骤：

  1. 使用$ pip uninstall amqp卸载amqp。
  2. 使用$ pip install -Iv amqp==2.1.3安装amqp。
