芹菜项目没有属性“应用程序”

Question

我已经创建了一个简单的芹菜项目。结构如下：

+--parent 
| +--sm 
| | +--__init__.py 
| | +--celery.py 
| | +--celeryconfig.py 
| | +--tasks.py 
| +--__init__.py 
| +--runner.py 
| +--numlist.csv 

celery.py：

from future import absolute_import 
from celery import Celery 
app = Celery("sm") 
app.config_from_object('sm.celeryconfig') 
app.conf.update(CELERY_TASK_RESULT_EXPIRES=3600,) 
if __name__ == '__main__': 
    app.start() 

celeryconfig.py：

from __future__ import absolute_import 
CELERY_IMPORTS=("sm.tasks") 
BROKER_URL = "amqp://guest:guest@localhost:5672//" 
CELERY_RESULT_BACKEND = "localhost:5672//" 
CELERY_ROUTES = {'sm.tasks.add_sub': {'queue': 'add_sub'}, 
     'sm.tasks.multiply':{'queue':'multiply'} 
     } 
CELERY_CREATE_MISSING_QUEUES = True 
CELERY_MESSAGE_COMPRESSION = 'bzip2' 
CELERYD_PREFETCH_MULTIPLIER = 1 
CELERY_DEFAULT_QUEUE = 'sm_celery' 

tasks.py：

from sm.celery import app 
import logging 
logger = logging.getLogger(__name__) 
logger.setLevel(logging.INFO) 

@app.task(queue='add_sub') 
def add_sub(line): 
    try: 
     a = int(line.split(",")[0]) 
     b = int(line.split(",")[1]) 
     sums = a+b 
     subs = a-b 
     return (sums, subs) 
    except Exception as e: 
     logger.error("Something wrong in add_sub. Inputs are line= 
     {0}".format(line)) 

@app.task(queue='multiply') 
def multiply(nos): 
    try: 
     a = nos[0] 
     b = nos[1] 
     return a*b 
    except Exception as e: 
     logger.error("Something wring in multiply. Inputs are nos= 
    {0}".format(nos)) 

我得到的错误当我尝试启动工作人员或检查celer的状态时Y：

celery -A sm status 

下面是错误：

Traceback (most recent call last): 
    File "c:\anaconda3\lib\site-packages\celery\app\utils.py", line 361, in 
find_app 
    found = sym.app 
AttributeError: module 'sm' has no attribute 'app' 

During handling of the above exception, another exception occurred:

运行Windows的计算机上。 Python版本：Python 3.5.2 :: Anaconda 4.1.1（64位）

Answer 1

在您的celery.py文件中，您是否尝试将下划线添加到future导入？例如：

from __future__ import absolute_import 
from celery import Celery 
app = Celery("sm") 
... 

目前无法访问Windows，但我尝试在Ubuntu机器上运行您的应用程序。进入ImportError直到我修复celery.py中的future导入。没有捕获任何AttributeErrors。
