laravel / framework v4.2.9需要d11wtq / boris~1.0 - ＆gt;找不到匹配的包

Question

我有以下composer.json：

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "require": {
        "laravel/framework": "4.2.*",
        "zizaco/entrust": "1.2.*@dev",
        "zizaco/confide": "~4.0@dev",
        "mailchimp/mailchimp": "~2.0",
        "guzzlehttp/guzzle": "~4.0",

        "yajra/laravel-datatables-oracle": "~3.0",
        "rap2hpoutre/laravel-log-viewer": "^0.5.3"
    },
    "require-dev": {
        "way/generators": "~2.3",
        "Codeception/Codeception": "~2.0",
        "league/factory-muffin": "^2.1"
    },
    "autoload": {
        "classmap": [
            "app/commands",
            "app/controllers",
            "app/models",
            "app/database/migrations",
            "app/database/seeds",
            "app/tests/TestCase.php"
        ],
        "psr-4": {
            "Benu\\": "app/Benu"
        }
    },
    "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",
        "bin-dir": "bin"
    },
    "minimum-stability": "dev",
    "prefer-stable": true
}

运行`composer install后，我收到以下错误：

  

laravel / framework v4.2.9要求d11wtq / boris~1.0 - >没有匹配   包找到了。

我在json中尝试过最小的依赖项：

"require": {
    "laravel/framework": "4.2.*"
},
"require-dev": {
    "way/generators": "~2.3"
},

但错误是一样的。这是完整输出：

知道怎么解决吗？
