python - 探戈与 Django ModuleNotFoundError : No module named 'registration'

Question

我已经克隆了 this存储库作为教程的一部分并进入目录 tango_with_django_19/code/tango_with_django_project 运行命令:

$ python maange.py runserver

为了运行网络应用程序。但是，我收到以下错误:

Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x7f6e2c1782f0>

  File "<frozen importlib._bootstrap>", line 948, in _find_and_load_unlocked
ModuleNotFoundError: No module named 'registration'

我正在使用 Manjaro Linux 并使用 pacman 安装了软件包 python-django 和 python-django-extensions。

如何解决此错误以便我可以运行网络应用程序？克隆上述 repo 后我没有改变。

您需要安装项目依赖。

在 tango_with_django_19/code 中运行 pip install -r requirements.txt 来安装它们。

然后迁移并运行服务器
