TypeError: "exports" is read-only

When I try loading vue-pdf in my App.Vue file, I get an odd looking error:

 import pdf from 'vue-pdf'
 export default {
     components: {
	 pdf	 
     },
...
}

TypeError: "exports" is read-only

I don’t have jslint enabled. Any ideas as to what might be causing this? It’s preventing me from being able to use vue-pdf, which looks really cool.

It compiles fine, so I only get these errors in the console at run time:

I tried to reproduce this error with webpack@2.3.3 without success. It seems that this error occurs when one mix esm (import/export) with CommonJS module (require/exports). Please give more details about the error (file/line number)
