I am have error on npm run production, and its killing me :(

/js/shapecss.js from UglifyJs Unexpected token: name (Accordion) [./~/shapecss/resources/assets/js/component/Accordion.js:1,0][/js/shapecss.js:19054,6]

I am using shapecss developed in laravel mix.

here is code is look like on main js entry file shape.js,
directory is, https://github.com/MicroDreamIT/shapecss-framework/blob/master/resources/assets/js/shape.js
'use strict';

import {Accordion} from "./component/Accordion";
import {Modal} from "./component/Modal";
import {getTab} from "./component/Tab";
import {Nav} from "./component/Nav";
import {Circle} from "./component/shapes/Circle";
import {Parallelogram} from "./component/shapes/Parallelogram";
import {Rectangle} from "./component/shapes/Rectangle";
import {Square} from "./component/shapes/Square";

window.onload = function () {
new Accordion();
new Modal();
getTab();
new Nav();
new Circle();
new Parallelogram();
new Rectangle();
new Square();
}
Accordion class is look like,

export class Accordion{
constructor(){
this.accordionDivs = document.getElementsByClassName('accordion');
if(this.accordionDivs)
this.processAccordions();
}
processAccordions() {
...
}

Is there more information? The line from above doesn't help too much + not very familiar with laravel mix
