Angular Material 2: None of the modules are recognised in Angular CLI

I am trying to setup the Angular Material 2 in a Angular CLI project. I'm using the last versions. I added the references in the module and component file but when I try to used it noting is working. I followed all the steps from the setup instructions from the documentation but still not working. And I have no errors.

I can give you an example for the Datepicker component.

import { MdDatepickerModule, MdNativeDateModule } from '@angular/material';
.
.
.
exports: [
   ...
    MdDatepickerModule,
    MdNativeDateModule,
   ...
  ],
  imports: [
   ...
    MdDatepickerModule,
    MdNativeDateModule,
   ...
]

Here is my main.ts

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'; 
import { AppModule } from './app/app.module';
import { environment } from './environments/environment';

if (environment.production) { 
  enableProdMode();
}
platformBrowserDynamic().bootstrapModule(AppModule);
