How to fix issue with "Nothing to compile." message

The problem:

---

If you using yeoman and grunt and compile your stylesheets with compass, you can come across the message:

"Nothing to compile. If you're trying to start a new project, you have left off the directory argument.
Run "compass -h" to get help."

My simple chat application uses Node.js and Angular.js

Because I like learning new things some times ago I decided to create project where I can learn new technologies like:

• AngularJS - [http://angularjs.org/]
• NodeJS - [http://nodejs.org/]
• Websockets - by using socket.io library [http://socket.io/]
• Browser notification (at the moment not working :) )
• Authentication via node.js (I'm using Passport library [http://passportjs.org/])
• Jade - as a node template engine [http://jade-lang.com/]
