当请求应用程序尝试从数据库获取数据的页面时，我收到此错误：
mod_fcgid: stderr: PHP Fatal error: Class 'Doctrine\\DBAL\\Platforms\\AbstractPlatform' not found in /var/www/vhosts/jonesandsacristan.es/httpdocs/vendor/doctrine/dbal/lib/Doctrine/DBAL/Platforms/MySqlPlatform.php on line 38
它在debian上运行
PHP 5.4.34-0+deb7u1 (cli) (built: Oct 20 2014 08:50:30)
