Getting Error with Roots theme after installation

I am getting error after installing Root theme. I am a web designer and I don’t have much knowledge with PHP, thats why I could not understand the problem. I would be grateful if you can help me by providing guideline to fix the error. You will be able to see the error here:

Please don’t hesitate to ask me if you have any query.

Thank you!

define('WP_ENV', 'development');

Also, Roots isn’t meant to be uploaded directly to your server (it sounds like maybe that’s what you did?).

The documentation at assumes you’re developing your theme on your local server.

Thanks for your help. The problem gone and its working well.
