djangoで設定するセロリ：app.config_from_object（ 'django.conf：settings'）が機能しません

Question

まず、Python 2.7、Django 1.9.12、Celery 4.0.2をプロジェクトに使用しています。
「Djangoの最初の手順」セロリチュートリアルに従っています。
これは私のceleryapp.pyです：

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() 

私はグローバル設定

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

そして、私は実際に私のプロジェクトの設定にアクセスすることができないと、それだけでこのように動作させることができます。私は

'django.conf:settings' 

を使用している場合は、私は私が間違って何をやっている

セロリワーカーを起動したとき、私はエラーを取得しますか？私は同じディレクトリからPythonシェルを実行しようとしました：

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() 

これはうまく動作します。

それが有用である可能性がある場合には、これは私のプロジェクト階層である：

Answer 1

たぶんセロリが間違ってインストールされています。私は新しい仮想環境を作りました。
