明天我有一个编码面试(我的第一次! super 兴奋/紧张)，我正在努力让我的一个旧项目恢复活力并进行更新:一个用 Django/Python 构建的 producthunt 克隆。
过去一切都运行良好，现在，在 git 将其克隆到 ubuntu virtualbox 并在其 virtualenv 中更新后，我遇到了以下错误，经过数小时的故障排除和研究类似问题后空手而归在stackoverflow上。任何帮助表示赞赏。
错误:'AttributeError:'Settings'对象没有属性'ROOT_URLCONF''
设置和输出:

最佳答案
解决了。有几件事不对劲。自从将 django 安装从 1.10 升级到 2.2 后，发生了很多变化。包括 URL 引用(即 django.conf.urls 与 django.urls)，并且必须重新运行 requirements.txt 以确保所有内容都已正确安装和更新。
