  <p>I think this is why I can not use express command on terminal.</p>
  
  <p>it is giving me below error while running command  </p>
  
  <pre><code>$ express -h 
  bash: /usr/bin/express: No such file or directory
  </code></pre>
  
  <p>I am using ubuntu 14.04. </p>
  
  <p>can anyone shade light on this? why i am getting 304?</p>
