If I follow the instructions and add the css files to the angular.json, this is what happens on build:

steps to reproduce:

ng new demo
cd demo
yarn add  devextreme devextreme-angular
// open editor and add css files to `angular.json` 
ng build

My Angular version:

Angular CLI: 6.0.0
Node: 8.11.1
OS: win32 x64
Angular: 6.0.0
... animations, cli, common, compiler, compiler-cli, core, forms
... http, language-service, platform-browser
... platform-browser-dynamic, router

webpack                           4.6.0

How can I prevent this error?

The root Angular CLI folder is now your project folder. So, you don't need to use '../' any more. We updated the Using the DevExtreme Angular Components with Angular CLI accordingly.

@GoshaFighten Thanks, that got it fixed, but it then directly landed me on: #776
Perhaps it's worth to mention that in the docs too? for the time it's still needed?
