title: Heroku node.js - no such file or directory, open '.env'
body: <p>I built an app using node.js and deployed it onto heroku but I keep getting the error in my heroku logs:</p>
  
  <p><code>{ [Error: ENOENT: no such file or directory, open '.env'] errno: -2, code: 'ENOENT', syscall: 'open', path: '.env' }</code></p>
  
  <p>This means that it is missing the environment variables. However, I did set my environment variables in heroku/dashboard/config_vars. Furthermore, if i type: <code>heroku config</code>, it shows me a list of my environment variables...</p>
  
  <p>Does anyone know what might be happening or what I can do?</p>
  
  <p>Note - I added '.env' to my '.gitignore'.</p>
  
  <p>Thx in advance!</p>
