title: Issue with Angular material library after updating to Angular 6
body: <p>When i tried to compile the app, it threw this error:</p>
  
  <p><code>ERROR in src/app/app.module.ts(15,5): error TS2304: Cannot find name 'MatToolbarModule'. src/app/app.module.ts(16,5): error TS2304: Cannot find name 'MatSidenavModule'. src/app/app.module.ts(17,5): error TS2304: Cannot find name 'MatButtonModule'. src/app/app.module.ts(18,5): error TS2304: Cannot find name 'MatIconModule'. src/app/app.module.ts(19,5): error TS2304: Cannot find name 'MatListModule'. src/app/app.module.ts(20,5): error TS2304: Cannot find name 'MatMenuModule'. src/app/app.module.ts(21,5): error TS2304: Cannot find name 'AuthModule'. src/app/app.module.ts(22,5): error TS2304: Cannot find name 'AppRoutingModule'. src/app/app.module.ts(24,5): error TS2304: Cannot find name 'MatGridListModule'. src/app/app.module.ts(25,5): error TS2304: Cannot find name 'FlexLayoutModule'.</code></p>
  
  <p>When I try to add material to project by <code>ng add @angular/material</code> it shows me this: </p>
  
  <blockquote>
    <p>Package "@angular/material" was found but does not support schematics.</p>
  </blockquote>
  
  <p>Does anyone find a solution for this?</p>
