title: Node.js installation error
body: <p>I have installed Node.js, NVM and NPM according to : <a href="https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-an-ubuntu-14-04-server" rel="nofollow">https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-an-ubuntu-14-04-server</a></p>
  
  <p>My working directory looks like this:</p>
  
  <p><strong>Working_Files\WebRTC</strong>  which contains the files:</p>
  
  <ul>
  <li>package.json</li>
  <li>server.js</li>
  </ul>
  
  <p>and </p>
  
  <p><strong>Working_Files\WebRTC\views</strong> which contains an index file:</p>
  
  <pre><code>index.ejs
  </code></pre>
  
  <p>In Working_Files\WebRTC, in order to run the server, using:</p>
  
  <pre><code>  node server.js
  </code></pre>
  
  <p>every time I have to repeat the process explained in the installation, otherwise I receive the error:</p>
  
  <pre><code> node server.js 
   The program 'node' can be found in the following packages:
    * node
    * nodejs-legacy
    Try: sudo apt-get install &lt;selected package&gt;
  </code></pre>
  
  <p>where the error does stand please?</p>
  
  <p>Thank you</p>
