Hi, I just created new NativeScript with Angular shared code project and added nativescript-geolocation dependencies.

@Component({

  templateUrl: './home.component.html',
  styleUrls: ['./home.component.css'],
})
export class HomeComponent implements OnInit {
  title = 'HelloNativeScriptAngular';

  constructor() { }

  ngOnInit() {
  }

  public enableLocationTap(){
      geolocation.isEnabled().then(function (isEnabled) {
        if (!isEnabled) {
            geolocation.enableLocationRequest(true, true).then(() => {
                console.log("User Enabled Location Service");
            }, (e) => {
                console.log("Error: " + (e.message || e));
            }).catch(ex => {
                console.log("Unable to Enable Location", ex);
            });
        }
    }, function (e) {
        console.log("Error: " + (e.message || e));
    });
  }
}

Some minor changes to this library are required (imports etc) to support nativescript 7. I did submit a PR, although it likely requires some care (backward compatibility issues) #268

Having the same issue here…

The plugin is already updated for {N} 7, it's been moved under new scope like all other NativeScript plugins.

https://www.npmjs.com/package/@nativescript/geolocation

you can install it with npm

npm i @nativescript/geolocation

and replace

import * as Geolocation from 'nativescript-geolocation'; // old

import * as Geolocation from '@nativescript/geolocation'; // new

Using @nativescript/geolocation fixes the problem. This information should be in the readme of this repo.
