title: ".../node_modules/rxjs/Rx" has no exported member 'throwError'
body: <p>Angular documentation speaks about a "<a href="https://angular.io/guide/http" rel="noreferrer">throwError</a>" class whose import statement looking like the following</p>
  
  <pre><code>import { Observable, throwError } from 'rxjs';
  </code></pre>
  
  <p>But my compiler is not able to find the class and is complaining with the following error message</p>
  
  <blockquote>
    <p>ERROR in src/app/shared/services/myservice.service.ts(3,10): error
    TS2305: Module '"D:/workspace/dev/MyProject/node_modules/rxjs/Rx"' has no exported member 'throwError'.</p>
