Question

我正在尝试使用 Django Celery 使用 RabbitMQ 配置计划任务。在为我的项目目录中的celery类和一些任务创建对象之后，当我尝试使用以下命令配置Worker时

“ celery -A myproj worker ”我得到以下追溯

Traceback (most recent call last):

WindowsError: [Error 87] The parameter is incorrect

在settings.py中，它有

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

在tasks.py中，它有

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

我正在使用 Django-1.8 ，芹菜-4.0 ， amqp = 2.1.1 其中 myporj 是我的Django项目名称

请帮我解决这个问题。

Answer 1

我也发现了这个错误。

原因很简单。芹菜4.x只是不支持窗户。

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

所以，我想你需要尝试早期版本或切换到Linux系统。

当我在Django-celery中执行“celery -A myproj worker”时遇到WindowsError：[错误87]
