Question

我的__init__.py文件

from __future__ import absolute_import, unicode_literals
from .celery import app as celery_app

__all__ = ('celery_app',)

我的celery.py文件

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

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings')
app = Celery('myproject')

app.config_from_object('django.conf:settings', namespace='CELERY')
app.autodiscover_tasks()

我的 /etc/supervisor/conf.d/celery.conf 文件：

[program:]
command=/home/user/venv/bin/celery -A myproject worker --loglevel=INFO
environment=PYTHONPATH=/home/user/project-folder
user=user
numprocs=1
autostart=true
autorestart=true
stdout_logfile=/home/user/logs/celery.log
stderr_logfile=/home/user/logs/celery.log
startssecs=10
stopwaitsecs = 600
stopasgroup=true
priority=100

这是celery.log

中错误消息的最后一部分

我不知道此配置有什么问题吗？

Answer 1

from django.conf import settings

app.config_from_object(settings, namespace='CELERY')

实际上settings进入那里。

Answer 2

您不应将自己的celery应用导入到您的__init__.py文件中。删除它，它将解决您无限的启动导入循环。本质上，您的celery应用程序启动了django设置模块的初始化，该初始化又加载了应用程序并尝试重新加载项目__init__.py文件，该文件加载了您的celery文件，然后尝试重新加载了设置文件，因为它尚未初始化反过来。。。（您知道了）。

Answer 3

删除句子时，我也遇到同样的问题

app.autodiscover_tasks()

然后它起作用。因此，我认为问题是由于此而发生的。也许我们应该指定此功能的配置。

Answer 4

万一它对某人有帮助-我有一个类似的问题，它是由on_configure类的重写Celery方法中的异常引起的。我认为阻止Celery._load_config方法正常执行的任何操作都可能导致“超出最大递归深度”错误。

Celery 4.2-Django RecursionError：超过最大递归深度
