title: HTTP plugin is not installed error with ionic
body: <pre><code>$ ionic cordova plugin add cordova-plugin-http
  $ npm install --save @ionic-native/http
  </code></pre>
  
  <p>The implementation is:</p>
  
  <pre><code>  constructor(private https: HTTP ) {
    }
  
    this.https.get('http://ionic.io', {}, {})
    .then(data =&gt; {
     this.httpData =data;
     console.log(data.status);
     })
     .catch(error =&gt; {
  
       console.log(error.status);
  
       });
  </code></pre>
  
  <p>And I get this error:</p>
  
  <blockquote>
    <p>[20:49:03] console.warn: Native: tried calling HTTP.get, but the HTTP plugin is not installed.
    [20:49:03] console.warn: Install the HTTP plugin: 'ionic plugin add cordova-plugin-http'</p>
