[Vuejs]-Cannot Import Ace Document Object in vue webpack project?

Finally, I solved this question after trying many ways.

I don’t know why I cannot import export interface from the namespace.
I found require function in ace.d.ts, So I changed

let doc = new Ace.Ace.Document('')

to

let Document = Ace.require('ace/document').Document

When I need Document Object, Just let document = new Document()

it works.

Hope this can help others which have the same question as me.

How I solved?

I search ace.js about exports.Document and found ace/document
