如何修复“ AttributeError：'设置'对象没有属性'ROOT_URLCONF'”

时间：2019-09-09 17:55:39

标签： python django python-3.x ubuntu

明天我将进行编码采访（我有史以来第一次！超级兴奋/紧张），我正在努力使我的一个旧项目重获新生并进行更新：一个用Django / Python构建的producthunt克隆。

一切正常运行，现在，将git克隆到ubuntu virtualbox中并将其更新到virtualenv中后，我陷入了以下错误，经过数小时的故障排除和处理后空手而归研究关于stackoverflow的类似问题。任何帮助表示赞赏。

错误：'AttributeError：'设置'对象没有属性'ROOT_URLCONF'

设置和输出：

已解决。有几处错误。由于将django安装从1.10升级到2.2，所以进行了很多更改。包括URL引用（即django.conf.urls与django.urls），并且必须重新运行requirements.txt以确保所有内容均已正确安装和更新。
