Django-Celery：工作人员不执行任务

Question

我一直试图用Celery，RabbitMQ，Django进行一些测试..

问题是，一旦我产生了一个工人，我使用django来发送一个任务，这要归功于工人收到的.delay（），但从工作中看，工人找不到那个名字的任务执行。奇怪的是，因为具有完全相同名称的任务是工作者应该能够执行的任务列表。

这是：

- ＆GT; settings.py

BROKER_HOST = "127.0.0.1" #IP address of the server running RabbitMQ and Celery
BROKER_PORT = 5672
BROKER_URL = 'amqp://'
CELERY_IMPORTS = ('notify')
CELERY_IGNORE_RESULT = False
CELERY_RESULT_BACKEND = "amqp"
CELERY_IMPORTS = ("notify")

- ＆GT; __init__.py（在通知模块下）

import celery
from celery import app as celery_app
from notify.user.tasks import send_email

- ＆GT; tasks.py（在通知模块下）

import os
from celery import Celery, task
from django.conf import settings

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'app.settings')

app = Celery('app')
app.config_from_object('django.conf:settings', namespace='CELERY')
app.config_from_object('app.settings')
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS, force=False)


@task()
def send_email(recepient, title, subject):
    print('sending email')

以下是我如何在我的项目的根部产生我的工作人员：

celery worker -n worker_one -l debug -A notify

以下是当工作人员收到我发送的任务通知时得到的错误：

The full contents of the message body was:
'[["Guillaume", "One title", "This is my subject"], {}, {"chain": null, "callbacks": null, "errbacks": null, "chord": null}]' (123b)
Traceback (most recent call last):
File "/Users/guillaumeboufflers/.pyenv/versions/smartbase/lib/python3.5/site-packages/celery/worker/consumer/consumer.py", line 561, in on_task_received
strategy = strategies[type_]
KeyError: 'notify.user.tasks.send_email'

这很奇怪，因为......

[tasks]
  . celery.accumulate
  . celery.backend_cleanup
  . celery.chain
  . celery.chord
  . celery.chord_unlock
  . celery.chunks
  . celery.group
  . celery.map
  . celery.starmap
  . notify.user.tasks.send_email

谢谢大家的帮助......
