Heroku deployment fails

[norbertogomez]

Hello, while trying to deploy the project to heroku using the button that provided in description I got this:

PHP Fatal error:  Uncaught Error: Class 'Symfony\Component\Dotenv\Dotenv' not found in /app/bin/console:20
Stack trace:
#0 {main}
  thrown in /app/bin/console on line 20

Any Ideas?

you need to set the APP_ENV environment variable when deploying on heroku

See #643

Closing as fixed by #643.
