Question

我正在尝试将Celery用于网站的后台工作。芹菜工作者从芹菜节拍或python manage.py shell接收任务。但是它不会在Received task处理之后继续进行。我的代码如下。

环境：Windows 10，Python 3.7.4，Celery 4.4.2

task.py

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

@shared_task
def check():
    print("I am checking execution")

celery.py

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

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'DjangoSample.settings')
app = Celery('DjangoSample')
app.config_from_object('django.conf:settings', namespace='CELERY')
app.autodiscover_tasks()

芹菜工人日志是这样的。

(venv) C:\Users\doo56\PycharmProjects\untitled1\DjangoSample>celery -A DjangoSample worker -l info

我可以看到工作人员接收到任务，但是直到成功，它才处理。我可以解决这个问题吗？

Django Celery工作人员已收到任务，但未执行任务
