python - 使用 Celery 2.6.0rc5 时出现 TypeError

Question

我正在使用 Celery 2.6.0rc5 ，并出现以下错误:

[2012-06-22 23:01:42,016: ERROR/MainProcess] Unrecoverable error: TypeError('handle_event() takes exactly 3 arguments (1 given)',)
Traceback (most recent call last):
  File "/home/bmh/celery/celery/worker/__init__.py", line 350, in start
    component.start()
  File "/home/bmh/celery/celery/worker/consumer.py", line 369, in start

    return callback(message)
  File "/home/bmh/kombu/kombu/messaging.py", line 482, in _receive_callback

  File "/home/bmh/kombu/kombu/messaging.py", line 454, in receive
    [callback(body, message) for callback in callbacks]
  File "/home/bmh/celery/celery/worker/consumer.py", line 397, in on_task_received
    [callback() for callback in on_task_callbacks]
TypeError: handle_event() takes exactly 3 arguments (1 given)

我pulled both kombu and celery from git just moments ago ，并在安装了 redis-server (2:2.2.12-1build1) 作为代理的 Ubuntu 12.04 LTS 上进行尝试。

我的配置(celeryconfig.py)是:

BROKER_URL = "redis://localhost:6379/0"
BACKEND_URL = BROKER_URL
CELERY_RESULT_BACKEND = "redis"
CELERY_REDIS_HOST = "localhost"
CELERY_REDIS_PORT = 6379
CELERY_REDIS_DB = 0

我的 worker (worker.py) 是:

#!/usr/bin/python2.7
from celery import Celery

celery = Celery()

celery.config_from_object('celeryconfig')

@celery.task(ignore_result=True)
def atest(data):
    print "Got data: %s" % data

if __name__ == "__main__":
    celery.start()

当我使用 $ ./worker.py worker 运行 worker 时，我从 python shell 中按如下方式调用该 worker:

import worker
worker.atest("abc")

工作人员报告上述错误，报告一个更长的错误，最终以工作人员退出以下错误结束:

[2012-06-22 23:01:43,025: WARNING/MainProcess] File "/home/bmh/kombu/kombu/utils/eventio.py", line 95, in unregister
[2012-06-22 23:01:43,025: WARNING/MainProcess] self._epoll.unregister(fd)
[2012-06-22 23:01:43,025: WARNING/MainProcess] ValueError
[2012-06-22 23:01:43,025: WARNING/MainProcess] :
[2012-06-22 23:01:43,026: WARNING/MainProcess] I/O operation on closed epoll fd

顺便说一句，当我运行 $ ./worker.py shell 并运行“import kombu; kombu.version”时，它报告 2.2.2，据我所知最新版本。可能还值得注意的是 someone else encountered this , 但似乎已经通过更新 kombu 解决了这个问题。

因为这真的是我能想象到的最简单的 celery 项目，我对 celery 完全陌生，而且这是一个开发版本，我对从这里去哪里有点困惑，如果有任何帮助，我将不胜感激。

我似乎已经通过更新到最新版本的 Billiard 解决了这个问题与:

$ git clone https://github.com/celery/billiard
$ cd billiard 
$ python setup.py develop
