title: Module not found: Error: Can't resolve 'rxjs/Rx'
body: <p>I am using angular CLI and visual studio code. 
  my suggested import for Observable is 
  <code>import { Observable } from 'rxjs/internal/observable';</code>
  although this does not import catch and throw.
  <code>import 'rxjs/add/operator/catch';</code>
  <code>import 'rxjs/add/observable/throw'</code>
  I went through a few issues raised which said to import from <code>import {Observable} from 'rxjs/Rx';</code>
  But this gives me Error </p>
  
  <blockquote>
    <p>Module not found: Error: Can't resolve 'rxjs/Rx'.</p>
  </blockquote>
  
  <p><code>Node version : v8.9.4</code></p>
  
  <p><code>npm version : 5.6.0</code></p>
  
  <p>I am just extremely new to angular and don't know what I am doing wrong or the corrective steps. 
  Please help.</p>
