Question

我将celery用于我的Django项目，并且要运行celery beat worker，请使用命令

celery -A <projectname> worker -B

这很好，但是如果我想从我的应用程序中执行此命令，则

我运行此命令

celery -A path\to\projectname worker -B

然后我收到此错误ImportError：不支持按文件名导入。

这是我的目录结构。

这是我的错误堆栈跟踪

有什么方法可以从我的应用程序中运行celery beat worker命令。希望能得到任何帮助

如果您位于Django应用程序的根目录中，并且已将celery应用程序添加到django设置中。您的celery.py文件应如下所示。

from __future__ import absolute_import
import os
from celery import Celery
from django.conf import settings
from my_django_app import settings as app_settings

# set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'my_django_app.settings')
APP = Celery('my_django_app', broker=app_settings.BROKER_URL)

# 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)

然后，您可以在Django根目录中以这样的方式运行命令

celery -A my_django_app worker -B

在我的Django应用程序中运行celery beat worker
