Configuration problems with django and mod_wsgi
提问by Jimbo
I've got problems on getting django to work on apache 2.2 with mod_wsgi. Django is installed and mod_wsgi too. I can even see a 404 page when accessing the path and I can login to django admin. But if I want to install the tagging module I get the following error:
我在使用 mod_wsgi 让 django 在 apache 2.2 上工作时遇到了问题。安装了 Django 和 mod_wsgi。我什至可以在访问路径时看到 404 页面，并且可以登录到 django admin。但是如果我想安装标记模块，我会收到以下错误：

I try to get this to work since a few days and have read several blogs and answers here on so but nothing worked.
几天以来，我尝试让它发挥作用，并且已经阅读了几个博客和答案，但没有任何效果。

Now I tried it with this blog postand my wsgi file now looks like this:
现在我用这篇博文尝试了它，我的 wsgi 文件现在看起来像这样：
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()
admin is still working, but I'm getting the same error when I try to install the tagging module.
admin 仍在工作，但是当我尝试安装标记模块时遇到了同样的错误。

First,
第一的，
- Since your admin works, the setting with wsgi is good. Don't bother changing/editing it.
- 由于您的管理员有效，因此 wsgi 的设置很好。不要打扰更改/编辑它。
To ensure that it is not a Apache/mod-wsgi setting problem, you can run the development server from the production machine
为确保不是Apache/mod-wsgi设置问题，可以从生产机器运行开发服务器
python manage.py runserver 0:8080
Then point your browser to
然后将您的浏览器指向
http://yoursite.com:8080/
You must see exactly the same behaviour.
您必须看到完全相同的行为。
Then,
然后，
For debugging this problem:
为了调试这个问题：
On the python shell on your server, try
import tagging. Clearly, from your traceback,import taggingis where it is raising an error and thats why, settings cannot be imported.Then, Just delete the package containing tagging, and do a fresh install by the following command, which knows how to install packages, well.
在服务器上的 python shell 上，尝试
import tagging. 显然，从您的回溯import tagging来看，它是引发错误的地方，这就是无法导入设置的原因。然后，删除包含标记的包，并通过以下命令进行全新安装，该命令知道如何安装包，好吧。

sudo pip install django-tagging

Have you read Graham Dumpleton's blog post on Django and WSGI? It does a pretty good job of describing some common configuration problems, and specifically touches on mysite.settingsvs. settings.
你读过 Graham Dumpleton关于 Django 和 WSGI的博文吗？它在描述一些常见的配置问题方面做得非常好，特别涉及mysite.settingsvs. settings.
UPDATE: Please read Graham Dumpleton's excellent comments below.
更新：请阅读以下 Graham Dumpleton 的精彩评论。
UPDATE 2: As both Graham and becomingGuru have pointed out, the problem is not with WSGI at all. It is instead a problem with your installation of django-tagging. Take becomingGuru's advice and use pipto install django-tagging.
更新 2：正如 Graham 和 BeingingGuru 所指出的，问题根本不在于 WSGI。相反，这是您安装的问题django-tagging。接受成为Guru的建议并使用pip安装django-tagging.
