symfony/profiler-pack 在安装后立即被删除

Question

我使用命令创建了一个项目 composer create-project symfony/website-skeleton my_project_name

我想安装symfony/profiler-pack. 为什么？因此，探查器中没有“调试”选项卡。

我试过使用composer require --dev symfony/profiler-pack，输出是

为什么symfony/profiler-pack安装后立即删除？

我的一部分composer.json：

"require-dev": {
    "symfony/browser-kit": "^5.1",
    "symfony/css-selector": "^5.1",
    "symfony/debug-bundle": "^5.1",
    "symfony/maker-bundle": "^1.0",
    "symfony/monolog-bundle": "^3.0",
    "symfony/phpunit-bridge": "^5.1",
    "symfony/stopwatch": "^5.1",
    "symfony/twig-bundle": "^5.1",
    "symfony/var-dumper": "^5.1",
    "symfony/web-profiler-bundle": "^5.1"
}

该*-packSymfony的包是“元套餐”，并在安装后，他们总是“删除”

它们的唯一目的是同时安装一堆一级相关的依赖，有时还会执行一些flex recipes。

当您require profiler-pack，实际添加到您的依赖项中的是：

"symfony/stopwatch": "5.1.*",
"symfony/twig-bundle": "5.1.*",
"symfony/web-profiler-bundle": "5.1.*",

您可以在 packagist 上检查确认这一点。

或者，例如，如果您安装，orm-pack您将在第一级安装这些（例如，这些现在是您项目的依赖项，而不是包的依赖项）：

"composer/package-versions-deprecated": "^1.11",
"doctrine/doctrine-bundle": "^2.1",
"doctrine/doctrine-migrations-bundle": "^3.0",
"doctrine/orm": "^2.7",

过去，这些包作为第一级依赖项安装，除非您将--unpack标志传递给require，或者您unpack在安装后执行。现在默认情况下这些包是解包的，这更好，否则“真正的”依赖项隐藏在 Symfony“元包”后面。

profiler-pack安装后删除的事实是完全正常的行为。你不能保留那个包，而且它也不会带来任何运行时特性。

您正在寻找的“调试”选项卡由不同的包提供，如msg 在评论中所述。它由 提供symfony/debug-bundle，您似乎已经安装了它。尽管安装了它，但它似乎不存在，您的安装可能由于某种原因过时。

但更有可能的是，您的bundles.php文件中未启用该包。确保它在那里：

Symfony\Bundle\DebugBundle\DebugBundle::class => ['dev' => true, 'test' => true],
