'package' 参数需要执行相对导入

Question

我不确定是什么导致了这个错误，我正在尝试从 Windows PowerShell 在 django 上运行，但我收到了这个错误和这一系列问题。

这是在我运行 python manage.py runserver 之后完成的

任何关于这个问题的帮助都会很棒

Answer 1

include('.upload.urls') 中的前导点导致了问题。

假设upload 在您的项目目录中（包含manage.py 的目录），将其更改为upload.urls 应该可以。

url(r'^upload/', include('upload.urls')),
