Can't resolve 'vertx'

[ubarevicius]

Using webcomponents-lite.js in polyfills.ts of Angular file gives this build time error

WARNING in ./node_modules/@webcomponents/webcomponentsjs/webcomponents-lite.js
Module not found: Error: Can't resolve 'vertx' in 'E:...\node_modules@webcomponents\webcomponentsjs'

We use es6-promise v4.2.4
Our application currently runs on Angular 5.2.0 with Angular CLI 1.7.0 and webpack 3.10.0

If I understand it correctly warning comes from webpack and not from cli. Let me know if you miss more info on this.

Thx.
