I'm trying to add AGM Angular Google Maps (https://github.com/SebastianM/angular-google-maps) to my Angular4 Project

Guide followed: https://github.com/SebastianM/angular-google-maps/blob/master/docs/getting-started.jade

The error I get when I visit the page with the agm component:

I have made sure/tried;

  • My module imports AgmCoreModule
  • Added CUSTOM_ELEMENTS_SCHEMA to SCHEMAS in my module (this had no effect)
  • Binding lat/lng values to literal integers

My site-map.component.ts:

import { Component, AfterViewInit, Injector, ViewEncapsulation, ViewChild, trigger, transition, style, animate, state,  } from '@angular/core';
import { Router, ActivatedRoute, Params } from '@angular/router';
import { Http } from '@angular/http';

import { appModuleAnimation } from '@shared/animations/routerTransition';
import * as moment from "moment";
import { JTableHelper } from '@shared/helpers/JTableHelper';
import { AgmMap, AgmMarker } from '@agm/core';

 var google: any; 

@Component({

    templateUrl: 'site-map.component.html',
    animations: [appModuleAnimation()]
})
export class SiteMapComponent extends AppComponentBase {


 title: string = 'My first AGM project';
      lat: number = 51.678418;
      lng: number = 7.809007;

    constructor(
        injector: Injector
    )
    {
        super(injector);
    }

}

My site-map.component.html

<agm-map [latitude]="lat" [longitude]="lng">
                    <agm-map-marker [latitude]="lat" [longitude]="lng"></agm-map-marker>

Any help is much appreciated.

This error occurs only when you have a child module for the components where you are implementing the map, So you need to add that module in your child module too without forRoot()

app.module.ts

import { AgmCoreModule } from '@agm/core';

@NgModule({
 imports: [
    AgmCoreModule.forRoot({
      apiKey: ''
   })
  ]
})

child.module.ts 

import { AgmCoreModule } from '@agm/core';

@NgModule({
 imports: [
    AgmCoreModule
  ]
})

This will work fine because now the child module has AgmCoreModule
