title: Composer Command not found after installing Homestaed
body: <p>I'm new to php and Laravel.</p>
  
  <p>I have installed Homestead as explained <a href="https://laravel.com/docs/5.4/homestead#configuring-homestead" rel="nofollow noreferrer">here</a></p>
  
  <p>when I access <a href="http://homestead.app/" rel="nofollow noreferrer">http://homestead.app/</a> it is working( Im getting "No input file specified")</p>
  
  <p>Then When I run # composer command inside the Homestead Directory, It says composer command not found.</p>
