python - 需要 'package' 参数来执行相对导入

Question

我不确定是什么导致了这个错误，我想尝试从 Windows PowerShell 在 django 上运行，但我遇到了这个错误和问题。

TypeError: the 'package' argument is required to perform a relative import for '.upload.urls'

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

对这个问题的任何帮助都会很棒

include('.upload.urls')中的前导点导致问题。

假设 upload位于您的项目目录中(包含 manage.py 的目录)，将其更改为 upload.urls应该管用。

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