用django配置芹菜：app.config_from_object（'django.conf：settings'）不起作用

Question

首先，我在我的項目中使用Python 2.7，Django 1.9.12和Celery 4.0.2。
我正在關注「Django的第一步」芹菜教程。
這是我celeryapp.py：

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

sys.path.append('vagrant/nested_tree/nested_tree_project') 

# set the default Django settings module for the 'celery' program. 
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'nested_tree_project.settings') 

app = Celery('nested_tree_project', broker='amqp://localhost//') 

# Using a string here means the worker don't have to serialize 
# the configuration object to child processes. 
# - namespace='CELERY' means all celery-related configuration keys 
# should have a `CELERY_` prefix. 
app.config_from_object('django.conf:global_settings', namespace='CELERY') 

# Load task modules from all registered Django app configs. 
app.autodiscover_tasks() 

我可以把它的工作只有這樣，全球設置

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

實際上我無法訪問我的項目設置。如果我使用

'django.conf:settings' 

我得到一個錯誤，當我開始芹菜工人

我在做什麼錯？我試圖從同一目錄運行python shell：

import sys, os, django 
sys.path.append('vagrant/nested_tree/nested_tree_project') 
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'nested_tree_project.settings') 
django.setup() 

它工作得很好。

在情況下，它可能是有用的，這是我的項目層次：

也許芹菜已裝錯了。我已經創建了新的虛擬環境並且現在可以工作。
