I am trying to get Yiistrap (Bootstrap for the Yii Framework) to work on Cent OS 6.5. I've unpacked the yiistrap-master into extensions/bootstrap and added the following to protected/config/main.php:
// uncomment the following to define a path alias
// Yii::setPathOfAlias('local','path/to/local-folder');
// CWebApplication properties can be configured here.
return array(
    'aliases'=>array(
    'bootstrap'=>'/var/www/html/happytails/protected/extensions/bootstrap'
    ),
 'import'=>array (
    'bootstrap.helpers.TbHtml',
  'components'=>array(
            'bootstrap'=>array(
            'class'=>'bootstrap.components.TbApi'
            ),
I also added the register function onto protected/views/layouts/main.php
<?php /* @var $this Controller */ ?>
<?php Yii::app()->bootstrap->register(); ?>
This should work but I keep running into the error:
Alias "bootstrap.components.TbApi" is invalid. Make sure it points to an existing PHP file and the file is readable.
File is there and readable. I am not sure what could be the issue.

Thank you very much for any help you can provide on this subject.
I had the same problem. You can fix it configuring all required directories for bootstrap in your main.php:
'import'=>array(
    ...
    'bootstrap.helpers.*',
    'bootstrap.widgets.*',
    'bootstrap.behaviors.*',
),
With Yiistrap 1.3.0 I had to do the following:
'import' => array(
    'bootstrap.helpers.TbHtml',
    'bootstrap.helpers.TbArray',
    'bootstrap.behaviors.TbWidget',
    'bootstrap.widgets.*'
)
