Django应用程序尚未加载芹菜任务

什么是给出下面的错误？我不确定这是否是我安装的应用程序或我的一个应用程序的问题。下面的例外情况仅在运行Celery时产生，即celery -A demo.apps.wall.tasks worker，runserver不会产生任何错误。哪个应用程序是这个问题？Django应用程序尚未加载芹菜任务

运行manage.py check是确定的。

什么是您的芹菜文件的样子 - 你设置里面Django的设置？这对于Django本身并不是问题（这就是manage.py检查很好的原因）。 –

@JensAstrup我将在一秒钟后发布芹菜任务文件：谢谢 – Prometheus

您使用的是哪个版本的Django？你从以前的版本升级？ – borfast

好的 - 发布你的芹菜应用程序文件后，我比较我所拥有的并尝试运行。认为我发现你的问题 - 它看起来像你在celery -A demo.apps.wall.tasks调用tasks.py。

如果您的墙模块包含celery.py和tasks.py - 您应该拨打celery -A demo.apps.wall。

这里的目录结构我有，和芹菜命令我运行：

django_project 
- an_app 
- celery_tasks 
    - init.py 
    - celery_app.py (celery.py in your case) 
    - tasks.py

我运行的命令：celery worker -A celery_tasks从django_project目录。

当我调用'celery -A demo.apps.celery worker'时，出现导入错误。 'ImportError：没有名为'memberships'的模块，但是celery.py不会导入成员资格，这很奇怪。直到我更新Django之前，这一切都在运行。我认为有些东西没有正确注册。 – Prometheus

你得到的全部回溯是什么？它应该显示你想要导入的位置/错误的位置。 –

尝试增加这的tasks.py开头：

import django 
django.setup()

celery.py模块不应该调用django.setup（），它在worker启动时由“django fixups”处理。 – Prometheus

升级到Celery 4和Django 1.10之后，我只能使用这个工具重新获得工作。 – acidjunk

这不适合我。这只会导致错误“RuntimeError：populate（）不可重入” – Cerin
