django-cms 产生“ImportError: cannot import name CacheKey”

Question

我最近更新了我的 django-cms（从 2.3.4 到 2.4），现在我不能再使用 ./manage.py（例如，使用 sqlall 语句）。这是输出

(venv)felipe@:~/Projects/heroku$ ./manage.py sqlall
Executing configuration file dev.py
Executing configuration file django_cms.py
Executing configuration file common.py
Traceback (most recent call last):

    from menus.models import CacheKey
ImportError: cannot import name CacheKey

traceback 中的应用是django-menus，django-cms relies 开启。不过，我已经看到 cms_tags 和其他人提出了同样的错误。有什么想法吗？

我再次重新启动了我的 virtualenv，一次安装了所有需要的组件，现在它可以工作了。 真的很神奇
