Django项目配置错误

Question

我刚开始学习Django，了解了基本的Django MVC架构。经过一些搜索，我发现我们应该按照下面的目录结构来组织项目，而不是使用django-admin.py startproject myproj和manage.py startapp app1自动生成的结构。

现在我的Django项目结构是这样的。（为了简化问题，我省略了一些内容，比如日志、fabfile等）

ROOT_DIR
    |-- manage.py
    |-- readme.txt
    |-- requirements.txt
    `-- webapp
        |-- apps
        |   |-- app1
        |   |   |-- admin.py
        |   |   |-- __init__.py
        |   |   |-- models.py
        |   |   |-- tests.py
        |   |   |-- urls.py
        |   |   `-- views.py
        |   |-- app2
        |   |   |-- admin.py
        |   |   |-- __init__.py
        |   |   |-- models.py
        |   |   |-- tests.py
        |   |   |-- urls.py
        |   |   `-- views.py
        |   `-- __init__.py
        |-- __init__.py
        |-- settings
        |   |-- __init__.py
        |   |-- common.py
        |   |-- development.py
        |   `-- production.py
        |-- static #CSS,JS,Images...
        |-- templates
        |-- urls.py
        `-- wsgi.py

wsgi.py

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "webapp.settings.development")

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

manage.py

import os,sys
if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "webapp.settings.development")
    from django.core.management import execute_from_command_line
    execute_from_command_line(sys.argv)

但是当我运行python manage.py runserver时，出现了这个错误。

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/home/eric/venv/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 399, in execute_from_command_line
    utility.execute()
  File "/home/eric/venv/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 392, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)
  File "/home/eric/venv/local/lib/python2.7/site-packages/django/core/management/base.py", line 242, in run_from_argv
    self.execute(*args, **options.__dict__)
  File "/home/eric/venv/local/lib/python2.7/site-packages/django/core/management/base.py", line 280, in execute
    translation.activate('en-us')
  File "/home/eric/venv/local/lib/python2.7/site-packages/django/utils/translation/__init__.py", line 130, in activate
    return _trans.activate(language)
  File "/home/eric/venv/local/lib/python2.7/site-packages/django/utils/translation/trans_real.py", line 188, in activate
    _active.value = translation(language)
  File "/home/eric/venv/local/lib/python2.7/site-packages/django/utils/translation/trans_real.py", line 177, in translation
    default_translation = _fetch(settings.LANGUAGE_CODE)
  File "/home/eric/venv/local/lib/python2.7/site-packages/django/utils/translation/trans_real.py", line 159, in _fetch
    app = import_module(appname)
  File "/home/eric/venv/local/lib/python2.7/site-packages/django/utils/importlib.py", line 40, in import_module
    __import__(name)
ImportError: No module named app2

我在development.py的开头和结尾放了一个检查打印语句。print INSTALLED_APPS

当我运行服务器时，它打印出了这个INSTALLED_APPS列表的所有值（也就是说，我在development.py中获取到的所有应用。INSTALLED_APPS变量在common.py中，而development.py是从common.py导入的）。

我不知道自己哪里出错了。（这是不是因为我把installed_apps变量用列表而不是元组？而且我使用了from common import *，但我觉得这个导入语句不是导致这个错误的主要原因。我是否需要导入其他东西，比如from __future__ import ...*）

附言：如果你对结构有任何建议，我非常欢迎，但我更关心这个错误。

编辑：

common.py

import os
import sys

BASE_DIR = os.path.dirname(os.path.dirname(__file__))
PROJECT_DIR = os.path.join(BASE_DIR, "webapp")

sys.path.append(PROJECT_DIR + '/apps')

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'south',
    'app1',
    'app2',
]
