Fatal error: Call to a member function writeBuffer() on a non-object in /var/www/website.local/views/layouts/default.ctp on line 31 

第31行为

echo $this->Js->writeBuffer(array('cache'=> true));

我在app_controller.php中有

<?php
class AppController extends Controller {
        var $helpers = array('Html','Form','Session','Js','Javascript');
        var $components = array(
                        'Session',
                        'RequestHandler',
                        'DebugKit.Toolbar'
                );
}
?>

看起来缺少一个组件文件：

ErrorHandler::missingComponentFile() - CORE/cake/libs/error.php, line 415

你可能想先研究一下这个错误，然后看看它是否能解决你的其他问题。
