  imports: [
     AgmCoreModule.forRoot({
          apiKey: 'YOUR_KEY',
          libraries: ['places']
        }),
     MatGoogleMapsAutocompleteModule.forRoot(), ...],  
  bootstrap: [AppComponent]
})
export class AppModule {

followed tutorial : link to tuto used

Solution : i don't know why and how but rolling back to an older version worked for me !! but that's not the proper solution i looking for

回答1:

You need to go back to a version that works.

In your package.json file, choose an older version specifically:

...    
"@types/googlemaps" :  "3.26.15"
...

I am getting the same error as defined above. but when I go to file in nodemodules/@types/GoogleMaps and open file index.d.ts. I see lot of functions there as shown in fig. for example we have a function bounds_changed: []; when I changed this function to bounds_changed:[''] it is working fine but we need an exact solution how to fix this because we are installing node modules every time when we create a build.

interface MapHandlerMap { /** * This event is fired when the viewport bounds have changed. * @see {@link https://developers.google.com/maps/documentation/javascript/reference/map#Map.bounds_changed Maps JavaScript API} * @see {@link Map#getBounds} * @see {@link Map#fitBounds} * @see {@link Map#panToBounds} */ bounds_changed: [];

    /**
     * This event is fired when the map center property changes.
     * @see {@link https://developers.google.com/maps/documentation/javascript/reference/map#Map.center_changed Maps JavaScript API}
     * @see {@link MapOptions#center}
     * @see {@link Map#getCenter}
     * @see {@link Map#setCenter}
     */
    center_changed: [];

downgrade your version of googlemapps https://www.npmjs.com/package/@types/googlemaps/v/3.38.0

run the command npm i @types/googlemaps@3.38.0
