把下载下来的bootstrap解压之后的整个文件夹,拷贝到项目中的protected\extensions文件夹里面,并且命名为bootstrap。 修改config目录下的main.php配置文件,修改完成之后的代码如下:

'preload'=>array('log','bootstrap'),


'gii'=>array(
    'class'=>'system.gii.GiiModule',
    'password'=>'password',
    // If removed, Gii defaults to localhost only. Edit carefully to taste.
    'ipFilters'=>array('127.0.0.1','::1'),
    'generatorPaths'=>array(
        'bootstrap.gii', // since 0.9.1
    ),
),


// application components
'components'=>array(
    'user'=>array(
        // enable cookie-based authentication
        'allowAutoLogin'=>true,
    ),
    // uncomment the following to enable URLs in path-format
	
    'bootstrap'=>array(
         'class'=>'ext.bootstrap.components.Bootstrap', // assuming you extracted bootstrap under extensions
     ),
