Need help to setup google autocomplete cities in meteor angular2 project

I’m seeing several issues while setting up google autocomplete in my meteor angular2 application. I’m trying to add this autocomplete to angular2 -meteor tutorial project (https://angular-meteor.com/tutorials/socially/angular2/bootstrap). I’m seeing issues like ‘cannot find namespace google or cannot find ElementRef.’

Please help me on how to add this autocomplete to my project
