芹菜项目没有属性'app'

Question

我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))

当我尝试启动工人或检查芹菜的状态时，我收到错误：

celery -A sm status

下面是错误：

Traceback (most recent call last):
File "c:anaconda3libsite-packagesceleryapputils.py", line 361, in 
find_app
found = sym.app
AttributeError: module 'sm' has no attribute 'app'

在您的celery.py文件中，您是否尝试过在导入future中添加下划线？ 例如：

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

现在无法访问Windows，但我尝试在Ubuntu机器上运行您的应用程序。 遇到了导入错误，直到我在celery.py中修复了future导入。 没有捕获任何属性错误。
