资产转储触发器[Twig_Error_Loader]

Question

当我尝试为我的生产模式生成css和javascript文件时：

php app/console assetic:dump --env=prod

我遇到了以下问题

[Twig_Error_Loader] 
The "/Applications/MAMP/htdocs/Symfony/vendor/symfony/swiftmailer-bundle/Sy  
mfony/Bundle/SwiftmailerBundle/Resources/views" directory does not exist.

是的，它确实不存在。无论如何为什么要找这个文件？

有关我使用以下版本的更多信息

复制我的composer.json文件的粘贴

"require": {
    "php": ">=5.3.3",
    "symfony/symfony": "2.3.*",
    "doctrine/orm": "~2.2,>=2.2.3",
    "doctrine/doctrine-bundle": "1.2.*",
    "twig/extensions": "1.0.*",
    "symfony/assetic-bundle": "2.3.*",
    "symfony/swiftmailer-bundle": "2.3.*",
    "symfony/monolog-bundle": "2.3.*",
    "sensio/distribution-bundle": "2.3.*",
    "sensio/framework-extra-bundle": "2.3.*",
    "sensio/generator-bundle": "2.3.*",
    "incenteev/composer-parameter-handler": "~2.0",
    "friendsofsymfony/user-bundle": "dev-master",
    "hwi/oauth-bundle": "0.4.*@dev"
},

我使用编辑器更新组件但仍然遇到同样的问题。
