Python Django：“；未安装标签为'的应用程序；flatpages'&引用；用django降价

我正在尝试向我的Django网站添加一个功能，该功能实现了管理员写的带有一些降价的文章

我安装了django markdown，并遵循本教程：

我进行了Migrations/migrate并运行了服务器，我成功地访问了我的网站，但是当我尝试访问管理界面时，我遇到了一个问题，说：

未安装标签为“flatpages”的应用程序。

以下是my requirements.txt的内容：

Django==1.7.5
django-markdown==0.8.4
Markdown==2.6
wheel==0.24.0

我假设它是来自django_markdown模块的flatpages。 我尝试了一些方法，比如在已安装的应用程序中添加“flatpages”。但这并不能解决问题（而且“django_降价”已经存在）。 我没有足够的django经验来理解我的项目中发生了什么，我需要一些帮助来理解这个问题。 有人能帮我吗

以下是一些可能有用的附加信息和文件： 错误：

可能是什么？我能做什么？
谢谢你的帮助。：）

编辑： 问题解决了，但为了解释模板中的标记，我还必须安装django markdown deux:
flatpages应用程序是。您需要正确安装它。从官方安装文档：

要安装flatpages应用程序，请执行以下步骤：

通过将

'django.contrib.sites'

添加到您的

已安装的应用程序设置中安装站点框架（如果尚未安装）
