這是我celery.py

from __future__ import absolute_import 
import os 
from celery import Celery 

# set the default Django settings module for the 'celery' program. 
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'clicknstrip.settings.local') 

from django.conf import settings 

app = Celery('clicknstrip') 

# Using a string here means the worker will not have to 
# pickle the object when using Windows. 
app.config_from_object('django.conf:settings') 
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS) 


@app.task(bind=True) 
def debug_task(self): 
    print('Request: {0!r}'.format(self.request))

這是我task.py

from __future__ import absolute_import 

from celery import shared_task 


@shared_task 
def add(x, y): 
    return x + y 


@shared_task 
def mul(x, y): 
    return x * y 


@shared_task 
def xsum(numbers): 
    return sum(numbers)

找到了我的問題，因爲我在增加了一個額外的逗號

CELERY_RESULT_BACKEND ='djcelery.backends.database：DatabaseBackend'，
