无法使用 Laravel 安装 Dingo

Question

我刚刚删除了我安装的 Laravel 文件夹，我在其中轻松安装了 Dingo 和 JWT。Laravel 版本是 5.2.x。

现在，每当我尝试重新安装 Dingo API 时，它都会给我错误。这是我使用的命令列表：

安装步骤

1. 安装 Laravel：composer create-project laravel/laravel citycare 5.2.*. （我也试过 5.1.*）
2. 安装 Dingo：composer require dingo/api:1.0.x@dev.

这是错误

You are running composer with xdebug enabled. This has a major impact on runtime performance. See https://getcomposer.org/xdebug

Installation failed, reverting ./composer.json to its original content.

Andrey B，我试过了，但这对我不起作用。显然，我决定继续尝试更多的东西以使其工作。这是我找到的解决方案：

我"phpdocumentor/reflection": "3.x@dev"在"require": { }in下添加composer.json并运行了一个composer update.

之后，composer require运行成功。

我仍然无法找到导致此问题的原因。我猜，上次我安装时，composer.json 里面已经有 phpdocumentor 了。

看看我的新composer.json：

        }
    },
    "autoload-dev": {
        "classmap": [
            "tests/TestCase.php"
        ]
    },
    "scripts": {
        "post-root-package-install": [
            "php -r \"copy('.env.example', '.env');\""
        ],
        "post-create-project-cmd": [
            "php artisan key:generate"
        ],
        "post-install-cmd": [
            "Illuminate\\Foundation\\ComposerScripts::postInstall",
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "Illuminate\\Foundation\\ComposerScripts::postUpdate",
            "php artisan optimize"
        ]
    },
    "config": {
        "preferred-install": "dist"
    }
}

还要注意我正在使用Laravel 5.1.x.
