Angular 7 - service worker not registered

Question

I did everything as written in "https://angular.io/guide/service-worker-getting-started" to make my application PWA.

Used exactly this commands:

ng add @angular/pwa

npm install http-server -g

ng build --prod

http-server -p 8080 -c-1 dist

Then I opened this url on Chrome (in incognito)

http://127.0.0.1:8080

When I open tools for developers (f12) > Applications > Service Workers there is no service worker available and website don't work when I set offline there.

Additional info about my angular app:

package.json: (the most important ones)

"@angular/core": "^7.0.2",
"@angular/pwa": "^0.10.6",
"@angular/service-worker": "^7.0.4",
"@angular-devkit/build-angular": "^0.10.6",
"@angular/cli": "^7.0.6",

It seems the service worker setup is broken for the @angular/cli@7.1.4:

As a temporary solution you can register it manually yourself by modifying the file src/main.ts (Once fixed you can remove the manual service worker registration.):

.....

platformBrowserDynamic().bootstrapModule(AppModule).then(() => {
  if ('serviceWorker' in navigator && environment.production) {
    navigator.serviceWorker.register('/ngsw-worker.js');
  }
}).catch(err => console.log(err));
