django没有名为wiki的模块

好的，所以我将跟随有关如何使用django制作Wiki进行实践的教程。我将Python 2.7与Django 1.6.4结合使用。我正在尝试运行服务器，以便可以刷新页面，但是突然间我收到了错误消息"ImportError: No module named wiki."

我已经搜索了这里所有的答案，很奇怪的是，我的项目中有一个名为Wiki的子目录，其中有一个__init__.py文件。这是我的目录的样子：

wikicamp (project)
    wiki
        __init__.py
        admin.py
        models.py
        tests.py
        views.py
    wikicamp
        __init__.py
        settings.py
        urls.py
        wsgi.py
    dbsqlite3
    manage.py

我的settings.py文件INSTALLED_APPS如下所示：

INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'wiki',

）

我已经尝试过将它作为'wikicamp.wiki'和as 'wiki'，并且两者都得到了相同的结果。它甚至不让我启动开发服务器，输入时出现错误python manage.py runserver。我确保我在正确的目录中。

这是我从中得到的所有信息：
