Question

我需要在django admin中为我的模型添加版本控制，因此我从here安装了django-reversion。我的服务器没有互联网连接，所以我无法使用pip。我不得不从github手动下载zip文件，将其上传到我的服务器，提取内容并运行python setup.py install以安装reversion。

但是，当我尝试导入它时，出现以下错误：

根据github页面，当前的版本是1.8.0，应该与django 1.6兼容。可能是什么问题？

我知道这是一个老问题，但万一有人偶然发现它：这里的问题是你运行的是标准的python解释器，而不是Django shell。您可以import django进入常规python解释器来检查Django版本，但它没有设置正确运行django所需的所有各种环境变量 - 包括导入django应用程序。要导入django应用程序，您需要通过

运行Django shell

./ python manage.py shell

导入django reversion会出错
