title: Unexpected Rxjs VueRx error in created hook
body: <p>I recently started working with VueRx and Rxjs. I am in the process of setting the basic. Somehow it gives me this error.</p>
  
  <pre><code>[Vue warn]: Error in created hook: "TypeError: 
  rxjs__WEBPACK_IMPORTED_MODULE_0__.Observable.interval is not a 
  function"
  
  found in
   ---&gt; &lt;Home&gt; at src/views/Home.vue
  </code></pre>
  
  <p>So I did the basic stuff as shown in the documentation. But It’s now working.
  This is what I have set up in <code>main.js</code>:</p>
  
  <pre><code>import * as Rx from 'rxjs'; 
  // I tried without * and with * both not working
  import VueRx from 'vue-rx';
  
  Vue.use(VueRx, Rx);
  </code></pre>
  
  <p>and this is how my component looks like:</p>
  
  <pre><code>&lt;template&gt;
   &lt;div class="home"&gt;{{ countdown$ }}&lt;/div&gt;
   &lt;/template&gt;
  
  &lt;script&gt;
  import { Observable } from 'rxjs';
  export default {
   subscriptions() {
     const countdwon$ = Observable.interval(1000);
    countdwon$.pipe(100);
    return {
       countdwon$,
      };
    },
  };
  &lt;/script&gt;
  </code></pre>
