Hi, i’m following a josh morony tutorial about adding service workers to your ionic 4 app: https://www.joshmorony.com/create-a-pwa-with-angular-service-workers-in-ionic-4/ On of the first steps is to execute: ng add @angular/pwa --project < app-name > However this results in the following error: […
