Ошибка после обновления Symfony с 2.5.8 до 2.6

Я только что обновил symfony 2.5.8 до 2.6, и у меня есть эта ошибка:

SCREAM: Error suppression ignored for
( ! ) Warning: require(D:\wamp\www\agence\vendor/symfony/intl/Symfony/Component/Intl/Resources/stubs/functions.php) 
[<a href='function.require'>function.require</a>]: 
failed to open stream: No such file or directory in D:\wamp\www\agence\vendor\composer\autoload_real.php on line 54

и это композитор

"require": {
    "php": ">=5.3.3",
    "symfony/symfony": "2.6.*",
    "doctrine/orm": "~2.2,>=2.2.3,<2.5",
