我按照[ http://docs.celeryproject.org/en/latest/getting-started/first-steps-with-celery.html ]中给出的所有步骤进行了操作.这是代码:

from __future__ import absolute_import
from celery import Celery

#app = Celery('tasks', broker='pyamqp://guest@localhost//')
app = Celery('tasks', backend='redis://localhost', broker='pyamqp://guest@localhost//')
@app.task
def add(x, y):
   return x + y

当我使用以下命令运行芹菜工作者时

celery -A tasks worker --loglevel=info

设置后端时出现语法错误.这是错误消息:
