title: NodeJS can't see LESS although it was installed with global opition
body: <p>I installed nodejs
  I installed npm
  I installed less with <code>-g</code> option</p>
  
  <p>but when I run nodejs via console and write command <code>less</code>, there is:</p>
  
  <pre><code>ReferenceError: less is not defined

  <p>I can run <code>less</code> or <code>lessc</code>, but outside nodejs</p>
  
  <p>to answer for replies:</p>
  
  <pre><code>var less = require('less');
