I don't know why the module is not imported. I'm using Python 2.7 and Django 1.4.
我不知道为什么没有导入模块。我使用的是 Python 2.7 和 Django 1.4。

It's actually also present in the 1.4 series since 1.4.2. You should really be using the latest 1.4.X release (1.4.10 as of the time of this writing) as earlier versions have known security vulnerabilities.
从 1.4.2 开始，它实际上也出现在 1.4 系列中。您真的应该使用最新的 1.4.X 版本（在撰写本文时为 1.4.10），因为早期版本存在已知的安全漏洞。

I ran into this issue when I wanted to use Django for Graphite. Turns out I had Django 1.3 installed and my Graphite version was breaking with Django > 1.5, so installing the latest version of the 1.4 branch fixed the problem:
当我想将 Django 用于 Graphite 时，我遇到了这个问题。结果我安装了 Django 1.3 并且我的 Graphite 版本在 Django > 1.5 时崩溃了，所以安装最新版本的 1.4 分支解决了这个问题：
sudo pip install --upgrade 'Django<1.5'
