Trying to interagret into third-paty tool - npm run dev failing

I am trying to integrate webix jet into an existing projects webpack tool chain. I am getting this error when I do a npm run dev

only when this line is added/enabled in the app.js:

import {JetApp, EmptyRouter, HashRouter } from “webix-jet”;

"./node_modules/webix-jet/dist/es6/jet.js" contains a reference to the file "jet-views".
This file can not be found, please check it for typos or update it if the file got moved.

"./node_modules/webix-jet/dist/es6/jet.js" contains a reference to the file "jet-locales".
This file can not be found, please check it for typos or update it if the file got moved.

Thoughts?
