python - 带有Django ModuleNotFoundError的探戈:没有名为“registration”的模块

作为教程的一部分，我克隆了this存储库，并进入tango_with_django_19/code/tango_with_django_project目录运行命令：

$ python maange.py runserver

以便运行Web应用程序。但是，我收到了以下错误：

ModuleNotFoundError: No module named 'registration'

我使用的是manjaro linux，并在pacman中安装了python-django和python-django-extensions包。
如何解决此错误以便运行Web应用程序？克隆上述回购协议后，我没有改变。

最佳答案

您需要安装项目依赖项。
在tango_中运行pip install -r requirements.txt和'u django_19/代码安装它们。
然后迁移并运行服务器
