[TypeError：无法读取未定义的属性“GlobalWorkerOptions”]

Question

My version of pdfjs-dist: "pdfjs-dist": "^2.4.456" This is import my code:

import PDFJS from 'pdfjs-dist'
import pdfjsWorker from 'pdfjs-dist/build/pdf.worker.entry'

and when I call:

PDFJS.GlobalWorkerOptions.workerSrc = pdfjsWorker
this.loadingTask = PDFJS.getDocument({ data: self.pdfData })

It return this error: [TypeError: Cannot read property 'GlobalWorkerOptions' of undefined]

And I try to console this: PDFJS , it return undefinded

So when I try this solution in the internet, I add

<script src="https://cdnjs.cloudflare.com/ajax/libs/pdf.js/2.5.207/pdf.min.js"></script>

in my index.html and add var PDFJS = window['pdfjs-dist/build/pdf'];

Then it works perfectly...But I dont know why the first approach doesn't work for me...And I do not want use this from CDN because I think it's not stable for my project. So could you guys give me a point what I missed here? I tried to look around in node-modules to figure out but I still do not why i can't import PDFJS from 'pdfjs-dist' ;

I SOLVED MY PROBLEM I do not know if it is the root of problem or not, but I just simple change from import PDFJS from 'pdfjs-dist' to import * as PDFJS from 'pdfjs-dist' , and it work perfectly.
