Question

我正在使用Celery 2.6.0rc5，并收到以下错误：

[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):

    [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，我在Ubuntu 12.04 LTS上尝试这个，redis-server（2：2.2.12-1build1）作为经纪人安装。

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

我的工作人员（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调用worker如下：

import worker
worker.atest("abc")

工作人员报告上述错误，报告更长的错误，该错误最终以工人退出以下结束：

[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 23:01:43,026: 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。版本”时，它会报告2.2.2，我知道这是最新版本。值得注意的是someone else encountered this，但似乎通过更新kombu来解决它。

由于这是我能想象的最简单的芹菜项目，我对芹菜来说是全新的，这是一个开发版本，我对从这里去哪里感到有点难过，并且会感激任何帮助。

感谢您的阅读。

我似乎通过更新到Billiard的最新版本来解决这个问题：

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