angular 2 integrating google maps yields ''cannot find namespace 'google'" error

Question

I'm trying to add the google maps service in my angular 2 app , but I'm getting following error: Cannot find namespace 'google'.

As seen on similar questions, I defined declar var google: any outside the class and I'm loading the google-maps api like this:

imports: [
   AgmCoreModule.forRoot({
     apiKey: "AIzaSyBfPIuViPbFbOzByKGGNKSuvNrbocxNyqE",
     libraries: ["places"]
   }),
   ...
]

I also installed typings install dt~google.maps --global , but it's still not working.

Answer 1

After adding

/// <reference path="./../../../typings/globals/google.maps/index.d.ts"/>

into the class in which I used google.maps , everything worked fine.
