在settings.py中有

app = Celery('assigner',
             broker='amqp://myuser:mypass@localhost/my_Vhost',
             backend='rpc://',
             include=['assigner.tasks'])

在tasks.py中，有

from __future__ import absolute_import
from assigner.celery import app
import time

@app.task
def longtime_add(x, y):
    print 'long time task begins'
    # sleep 5 seconds
    time.sleep(5)
    print 'long time task finished'
    return x + y

我用 django - 1.8 , 芹菜- 4.0 , amqp = 2.1.1 其中myporj是我的Django项目名

请帮我解决这个问题

Answer 1

我也发现这个错误。

原因很简单。芹菜4。X就是不支持windows。

http://docs.celeryproject.org/en/latest/faq.html does-celery-support-windows .

所以，我猜你需要尝试更早的版本或切换到linux系统。
