Django与mod_wsgi的配置问题

Question

我在用Apache 2.2和mod_wsgi配置Django时遇到了一些问题。Django和mod_wsgi都已经安装好了。我能看到404页面，也能登录Django的管理后台。但是，当我想安装标签模块时，就出现了以下错误：

 Traceback (most recent call last):
   File "setup.py", line 49, in <module>
  version_tuple = __import__('tagging').VERSION
   File "/home/jim/django-tagging/tagging/__init__.py", line 3, in <module>

   File "/usr/lib/python2.5/site-packages/django/conf/__init__.py", line 40, in _setup
  self._wrapped = Settings(settings_module)
   File "/usr/lib/python2.5/site-packages/django/conf/__init__.py", line 75, in __init__
  raise ImportError, "Could not import settings '%s' (Is it on sys.path? Does it have syntax errors?): %s" % (self.SETTINGS_MODULE, e)
 ImportError: Could not import settings 'mysite.settings' (Is it on sys.path? Does it have syntax errors?): No module named mysite.settings

这是我的httpd.conf配置文件：

 Alias /media/ /home/jim/django/mysite/media/

 <Directory /home/jim/django/mysite/media>
  Order deny,allow
  Allow from all
 </Directory>

 Alias /admin/media/ "/usr/lib/python2.5/site-packages/django/contrib/admin/media/"

 <Directory "/usr/lib/python2.5/site-packages/django/contrib/admin/media/">
  Order allow,deny
  Allow from all
 </Directory>

 WSGIScriptAlias /dj /home/jim/django/mysite/apache/django.wsgi

 <Directory /home/jim/django/mysite/apache>
  Order deny,allow
  Allow from all
 </Directory>

这是我的django.wsgi文件：

import sys, os

sys.path.append('/home/jim/django')
sys.path.append('/home/jim/django/mysite')

os.chdir('/home/jim/django/mysite')
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

我尝试了几天想让这个工作，读了好几个博客和这里的回答，但都没有成功。

编辑：

现在我试着按照这篇博客的内容修改我的wsgi文件，现在看起来是这样的：

import sys
sys.path.insert(0, '/home/jim/django/mysite')
sys.path.insert(0, '/home/jim/django')

import settings

import django.core.management
django.core.management.setup_environ(settings)
utility = django.core.management.ManagementUtility()
command = utility.fetch_command('runserver')

command.validate()

import django.conf
import django.utils

django.utils.translation.activate(django.conf.settings.LANGUAGE_CODE)

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

管理后台还是能用，但当我尝试安装标签模块时，还是出现了同样的错误。
