ImportError：沒有名爲'tasks'的模塊

Question

我試圖讓芹菜使用django來設置計劃任務。我試過看過the first steps w/ Celery和the first steps w/ Django教程，但都沒有爲我工作。這裏是我的項目佈局相關文件：

的Python 3.5.1

Django的1.10

芹菜4.0.2

的RabbitMQ 3.6.6

OTP 19.2

mysite/ (project name) 
    polls/ (myapp) 
     tasks 
     ... 
    mysite/ 
     __init__ 
     celery 
     settings 
     ... 
    manage 
    ... 

mysite/__ init__.py：

個

from __future__ import absolute_import, unicode_literals 

# This will make sure the app is always imported when 
# Django starts so that shared_task will use this app. 
from .celery import app as celery_app 

__all__ = ['celery_app'] 

民調/ celery.py：

from __future__ import absolute_import, unicode_literals 
import os 
from celery import Celery 

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

app = Celery('mysite', backend='amqp', broker='amqp://guest@localhost//',include=['polls.tasks']) 

# Using a string here means the worker don't have to serialize 
# the configuration object to child processes. 
# - namespace='CELERY' means all celery-related configuration keys 
# should have a `CELERY_` prefix. 
app.config_from_object('django.conf:settings', namespace='CELERY') 

# Load task modules from all registered Django app configs. 
app.autodiscover_tasks() 


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

民調/ tasks.py：

# Create your tasks here 
from __future__ import absolute_import, unicode_literals 
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) 

我試圖運行：

\mysite> celery -A tasks worker --loglevel=info 

，結果是：

ImportError: No module named 'tasks' 

Answer 1

的問題是在這條線：

\mysite> celery -A tasks worker --loglevel=info 

沒有tasks.py文件外的mysite文件夾：

我想你需要的是

\mysite> celery -A polls/tasks worker --loglevel=info 

或者：

\mysite> celery worker --app=mysite --loglevel=info 
\mysite> celery worker -A proj -loglevel=info 

執行此命令的位置是錯誤的。
