[Module] yii-environments

Hi,

I’m using this great extension:

http://www.yiiframework.com/extension/yii-environment/

Everything is working fine, however when I tried to use this code into the config file (config/main.php)




'clientScript' => array(

'scriptMap' => array(

'jquery.js'=>false,

'jquery.min.js'=>false,

),

'coreScriptPosition'=>CClientScript::POS_END,

),



I’m getting an error: Fatal error: Class ‘CClientScript’ not found in C:\xampp\htdocs\yii-locations\protected\config\main.php on line 56

Any suggestions??? help??
