我正在尝试使用composer安装behat和mink with symfony 2.4但是我似乎无法将我的composer.json文件解析为可安装的一组包.

我使用http://symfony.com/doc/current/book/installation.html上的命令安装了symfony2

php composer.phar create-project symfony/framework-standard-edition /path/to/webroot/Symfony 2.4.*

下面是我的composer.json文件的require部分:

"require": {
    "php": ">=5.3.3",
    "symfony/symfony": "~2.4",
    "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": "~2.4",
    "sensio/distribution-bundle": "~2.3",
    "sensio/framework-extra-bundle": "~3.0",
    "sensio/generator-bundle": "~2.3",
    "incenteev/composer-parameter-handler": "~2.0",
    "behat/behat":  "2.4.*@stable",
    "behat/mink":   "1.4.*@stable",
    "behat/symfony2-extension":      "*",
    "behat/mink-extension":          "*",
    "behat/mink-browserkit-driver":  "*",
    "behat/mink-selenium2-driver":   "*"
}

运行composer update后,我在屏幕上看到以下消息:

Loading composer repositories with package information
Updating dependencies (including require-dev)
