Sails.js is not working with forever
<p>I m new on both sails.js and node.js. 
I created a simple api with sails.js. It works fine when I start it with <code>sails lift --prod</code>. On the other hand when I start the application with <code>forever start app.js --prod</code> and it always returns 0 altough I dont not get any error and warning and I can see my app.js in the list with the forever list command.
I created a simple node.js application to test forever and it worked as expected. 
I tried to run my Sails.js application both my local windows and linux/ubuntu machine on digital ocean, they worked fine with sails lift but not forever. Also I tried <code>node app.js --verbose</code> and it was ok.  My sails version is 0.11.4. Thanx for your help.   </p>
