这个构建和数据库以前工作过。我检查了 settings.py 并安装了它抱怨的应用程序。此外，related_name 错误似乎是在引用它们自己。

我尝试使用django.contrib.contenttypes.management 模块中的update_all_contenttypes 方法清除内容类型并重新填充它们。该表现在似乎是正确的，但仍然出现这些错误。

【解决方案1】：

好的，在我发布这个之后我就明白了。在项目重组之前，我有一些流氓models.pyc 文件，它们定义了相同的模型但在不同的应用程序中。清除所有这些文件解决了这个问题。我猜我需要在我的部署过程中加入这部分内容。
