title: How to use SASS/ SCSS in Yii2?
body: <p>I want to use sass/scss in a new project, but it somehow doesn't work. 
  I am using the yii2-asset-converter and when I try to convert the scss-file, the following error is thrown: </p>
  
  <p><code>Class @app/extensions/assetparser/vendors/phamlp/sass/SassParser does not exist</code></p>
  
  <p>I am checking the path ../phamlp/ and notice, that the Folder sass resp. SassParser.php doesn't exist. 
  The SassParser.php is located in the extension  vendor/richthegeek/phpsass, which is required by yii2-asset-converter. </p>
  
  <p>I have tried out some paths like:
  <code>@ vendor/richthegeek/phpsass</code> or</p>
  
  <pre><code>__DIR__/../../vendor/richthegeek/phpsass
  </code></pre>
  
  <p>But it doesn't worked .After a lot of unsuccessful attempts I hope some of you know how to solve the problem. </p>
  
  <p>PS:I use the advanced app template</p>
