title: Install dependency (doctrine/dbal) on composer laravel
body: <p>I am trying to execute a migration to rename some columns and I got an exception. </p>
  
  <p>As I read on the documentation I have to add the doctrine/dbal dependency to my composer.json file. How do I do that? Which is the correct composer.json file. I have many in my application. Is the one that is on the same level as the folders app,bootstrap, public and vendor.</p>
  
  <p>If so how do I add that dependency. Do I have to download anything?</p>
  
  <p>By the way im using easyphp, not wamp!</p>
