title: RxJS6 (angular 6) - ERROR in node_modules/rxjs/Rx.d.ts(1,15): error TS2307: Cannot find module 'rxjs-compat'
body: <p>I recently update my application to angular 6 as well as the RxJs to <code>6.3.3</code> <code>version</code>. </p>
  
  <p>As described in <a href="https://auth0.com/blog/whats-new-in-rxjs-6/" rel="nofollow noreferrer">here</a>, I used the package <code>rxjs-compat</code> to have temporarily the code written in RxJS5 and RxJS6 compatibility mode, at the same time.</p>
  
  <p>As suggested by the RxJS team, after I update all my code to be compatible with RxJS6, I uninstalled the <code>rxjs-compat</code> because it is not longer necessary.</p>
  
  <p>After that, I'm trying to run my code but the compiler is retrieving the following error:</p>
  
  <blockquote>
    <p>ERROR in node_modules/rxjs/Rx.d.ts(1,15): error TS2307: Cannot find
    module 'rxjs-compat'</p>
  </blockquote>
  
  <p>Any one know what can be the problem in here? This seems that the RxJS pacadge depends on <code>rxjs-compat</code>, but if what I'm saying is true, why the RxJS team recommends to uninstall <code>rxjs-compat</code>?</p>
