Django Celery，应用程序导入错误仅在生产中

Question

我有这样的文件结构：

• 我的应用程序
  • 艺术家_应用程序
    • tasks.py
  • 任务
    • celery.py

# settings.py
INSTALLED_APPS = [
    'myapp.artist_application',
    ...

# celery.py
import os
from celery import Celery

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

# tasks.py

from tasks.celery import app as celery_myapp
from django.apps import apps
from django.conf import settings
import requests


@celery_esns.task(name='sample_task')
def sample_task():
    print('TESTING CELERY')

@celery_esns.task(name='publish_artist_task')
def publish_artist_task(payload, artist_id):
    r = requests.post(settings.PUBLISH_URL, json = payload)

    if r.status_code == 200:
        apps.get_model('artist_application', 'Artist').objects.filter(unique_id=artist_id).update(published=True)
    else:
        raise Exception("Error publishing artist with id: " + artist_id)

当我用以下方式启动 Celery 时，一切都运行良好：

celery -A myapp.tasks worker -Q celery -l info

但在生产中我运行命令（在 virtualenv 中），我得到了错误：

django.core.exceptions.ImproperlyConfigured: Cannot import 'artist_application'. Check that 'myapp.artist_application.apps.ArtistApplication.name' is correct.

任何想法去哪里看？我不明白“runserver”加载应用程序的方式与 wsgi 有何不同？

我必须将完整的虚线路径放在 apps.py 中

from django.apps import AppConfig

class ArtistApplicationConfig(AppConfig):
    name = 'myapp.artist_application'
    verbose_name = "Artist Application"
