使用IBM Bluemix进行Laravel数据库迁移

我试图将我的应用程序添加到使用IBM Bluemix的生产服务器。其实我是在免费的阶层，只是测试Bluemix。我的应用程序建立在Laravel 4.2上。使用IBM Bluemix进行Laravel数据库迁移

我已经创建了一个CLEARDB MySQL数据库和我编辑database.php中这样

首先，我添加了以下线顶端

<?php 

$services = json_decode(getenv('VCAP_SERVICES'), true); 
$sqlCreds = $services['cleardb'][0]['credentials']; 

return array(...

后来我调整了MYSQL配置

'mysql' => array(
       'driver' => 'mysql', 
       'host'  => $sqlCreds['hostname'], 
       'database' => $sqlCreds['name'], 
       'username' => $sqlCreds['username'], 
       'password' => $sqlCreds['password'], 
       'charset' => 'utf8', 
       'collation' => 'utf8_unicode_ci', 
       'prefix' => '', 
     ),

我还编辑了composer.json文件，以在推送项目时迁移数据库。

"scripts": { 
     "post-install-cmd": [ 
      "php htdocs/artisan clear-compiled", 
      "php htdocs/artisan optimize", 
      "php htdocs/artisan migrate --force" 
     ], 
     "post-update-cmd": [ 
      "php htdocs/artisan clear-compiled", 
      "php htdocs/artisan optimize" 
     ], 
     "post-create-project-cmd": [ 
      "php htdocs/artisan key:generate" 
     ] 
    },

但是，当我推送项目时，出现以下错误;

[PDOException]   
    could not find driver 
migrate [--bench[="..."]] [--database[="..."]] [--force] [--path[="..."]] [--package[="..."]] [--pretend] [--seed]

我是Bluemix的新手，无法找出问题。我相信在stackoverflow社区。任何帮助将不胜感激:)
