throw error when serve vue app if remove jquery dependency

[fayeah]

as the Document said 'No jQuery dependency'. But when I tried to remove jquery dependency from my vue project, then it throwed error as follows:

as the error message shows above: there includes sortablejs which is depended by draggble library.

So is there anything wrong with my understanding or what could I do to solve this problem if I have to remove jquery?

Thanks.
