title: Error while starting my project ( after running ng serve )
body: <p>I downloaded the zip file of the project from the online MOOC I am learning. It was working fine until now but now I am facing the error as described below :-</p>
  
  <p>I tried running <code>ng serve</code> again and also running <code>npm install</code> again but every time I encounter the following error:</p>
  
  <blockquote>
    <p>ERROR in node_modules/rxjs-compat/operator/shareReplay.d.ts(2,10):
    error TS2305: Module '"/Users/ratnabhkumarrai/Downloads/prj-http-final
    3/node_modules/rxjs/internal-compatibility/index"' has no exported
    member 'ShareReplayConfig'.</p>
  </blockquote>
  
  <pre><code>import { Observable, SchedulerLike } from 'rxjs';
  import { ShareReplayConfig } from 'rxjs/internal-compatibility';
  /**
  * @method shareReplay
  * @owner Observable
  */
  export declare function shareReplay&lt;T&gt;(this: Observable&lt;T&gt;, config: 
  ShareReplayConfig): Observable&lt;T&gt;;
  export declare function shareReplay&lt;T&gt;(this: Observable&lt;T&gt;, 
  bufferSize?: number, windowTime?: number, scheduler?: SchedulerLike): 
  Observable&lt;T&gt;;
  </code></pre>
