编辑 - 更新和总结：
pinax-project-teams 代码与 Django 1.7 不完全兼容，至少在新 Django 项目的初始“原始”安装时不兼容。解决方法包括几个步骤：
- 从
startup.py (line 21, in run()) 中移除显式/冗余应用加载：注释掉或删除admin.autodiscover()。
- 显式安装 Django 1.6.5 (
pip install Django==1.6.5)。
- 通过 django 1.6 版本 (
python manage.py syncdb) 同步数据库。
- 显式安装 Django 1.7.5 (
pip install Django==1.7.5)。
原答案帖：
我想我已经把它缩小了一点，如果不在范围内，至少在根本原因上。虽然我的项目不是从 Django pinax-project-team 中的某些内容使其默认与 Django 1.7 不兼容。在 1.6.5 django 安装上，相同的安装将允许 syncdb 和 runserver，但 django-1.7.5 会抛出 Apps aren't loaded yet。
我找到了很长的Django 1.7 release notes 列表，我正在开始查看是否可以确定不兼容的原因。
至少其中一个问题是 Pinax 在 startup.py 中的“额外”自动发现，在 Django 自己的启动过程中 as of 1.7 release is automatically executed。这解决了应用程序加载问题，看起来......但django.contrib.sites 中还有另一个问题。在 1.7 中运行 migrate 时，由于数据库中缺少表，其中一个迁移失败，特别是 django_site（下面的完整跟踪）。此表确实存在于 1.6 django 安装的数据库中。修改 1.7 的设置指向 1.6 项目中的 sqlite 文件解决了这个问题，瞧，它工作了。所以这是我在 pinax-project-teams 和 Django 1.7 之间发现的仅有的两个冲突。
