php - Composer 更新未在 Laravel 中安装 PHPUnit？

Question

我正在尝试安装PHPUnit进入Laravel框架通过 Composer 。

问题是运行composer update后没有下载所需的文件。

我的流程如下所示:

首先，我在 composer.json 中插入 PHPUnit 要求。整个文件如下所示:

{
    "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，我运行 composer update -vvv。转储看起来像这样(额外的奇怪之处:这是从命令提示符复制的，如果我执行相同的命令但尝试使用 > 命令将其写入 txt 文件，则过程会在 Downloading https:///packagist.org/packages.json 行)

最终所需的文件没有添加到 vendor/bin/ 中。据我所知，此时应该已经放置了一个名为 phpunit.php 的文件，但没有任何迹象。

Here is my composer.lock作为奖励信息，运行更新后没有任何 phpunit 的迹象。

添加PHPUnit失败的原因是你的composer.json中有两个名为“require”的键，这是非法的。最后一个实例会覆盖第一个实例 - 这会覆盖添加的 PHPUnit 要求。

只有将其更改为“require-dev”(这是一个不同的键)后，Composer 才能检测到您需要 PHPUnit。

{
    "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
    },

    // deleted lines here...

    "minimum-stability": "stable",
        "require": {
            "laravelbook/ardent": "dev-master"
        }

}

看到“require”作为 JSON 中最后一个缩进严重的键了吗？这至少会让 Composer 感到困惑。我很确定“laravelbook/ardent”依赖于“laravel/framework”和大量其他内容，因此您没有看到您的第一个 require 键被覆盖。

建议:始终使用命令行添加内容 - 这更容易，而且您不必注意正确的 JSON 格式:

composer require --dev phpunit/phpunit:~4.0

这会将依赖项添加到composer.json文件中，如果没有冲突，则立即下载它。它还将编写一个新的、格式清晰的composer.json 文件。如果 Composer 有机会删除双键，您就会很快发现错误。
