Composer更新不会在Laravel中安装PHPUnit？

我试图通过Composer将PHPUnit安装到Laravel框架中.

问题是运行composer update后未下载所需的文件.

我的流程如下:

首先,我在中插入PHPUnit要求composer.json.整个文件看起来像这样:

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "require": {
        "laravel/framework": "4.1.*",
        "laravelbook/ardent": "dev-master",
        "phpunit/phpunit": "4.2.*" // i have also tried with 3.7 and 3.8
    },
    "autoload": {
        "classmap": [
            "app/commands",
            "app/controllers",
            "app/models",
            "app/database/migrations",
            "app/database/seeds",
            "app/tests/TestCase.php",
            "app/filters"
        ]
    },
    "scripts": {
        "post-install-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-create-project-cmd": [
            "php artisan key:generate"
        ]
    },
    "config": {
        "preferred-install": "dist"
    },
    "minimum-stability": "stable",
        "require": {
            "laravelbook/ardent": "dev-master"
        }

}

接下来,我跑composer update -vvv.转储看起来像这样(Bonus Weirdness:这是从命令提示符复制的,如果我执行相同的命令但是尝试使用>命令将其写入txt文件,该过程在该Downloading https://packagist.org/packages.json行之后挂起)

C:\wamp\www\Dropbox\ltest>composer update -vvv

Nothing to install or update

并且最终不会添加所需的文件vendor/bin/.据我所知phpunit.php,此时应该放置一个名为的文件,但没有任何迹象.

这是我的composer.lock奖励信息,运行更新后没有任何phpunit的迹象.
