laravel在部署服务器中找不到类

Question

I have a Laravel 4 application working fine on my local machine. I've cloned it onto my VPS. When I run composer install or composer update, I get errors that "class not found". I've checked vendor/composer/autoload_classmap.php and my classes are there. The class is located in the standard app/models/. I removed some code, which finally allowed the composer to update. However none of my custom classes all located inside app/models are being loaded. Any ideas what's going on? Thanks.

Local: php version 5.5.10 VPS: php version 5.5.9

Edit: Included error log

[2014-10-23 02:50:37] production.ERROR: exception 'Symfony\Component\Debug\Exception\FatalErrorException' with message 'Class 'Role' not found' in ../app/routes.php:214
Stack trace:
#0 [internal function]: Illuminate\Exception\Handler->handleShutdown()
#1 {main} [] []

Role.php is located in app/models/

Edit2: Added route

Route::group(array('before' => 'auth.admin'), function() {

    $roles  = new Role();

    Route::get('/help', array(
        'as' => 'help',
        'uses' => 'HelpController@getHelp'
    ));
}

This isn't the full route, but that's essential it. Everything works fine on local machine also.

Answer 1

I found the problem with the help of others. MY VPS did not support short tags. My Role.php began with <? . I corrected it with <?php and everything works.
