symfony/profiler-pack（或 symfony/orm-pack，或其他一些 symfony/*-pack 软件包）在安装后立即被删除

Question

我已经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，分析器中没有“调试”选项卡。

我尝试过使用

composer require --dev symfony/profiler-pack

，输出是

Using version ^1.0 for symfony/profiler-pack
./composer.json has been updated

为什么

symfony/profiler-pack

安装后就被删除了？

我的

composer.json

的一部分：

"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"
}

*-pack

Symfony 软件包是“元软件包”，安装后它们总是被“删除”

它们的唯一目的是同时安装一堆一级相关依赖项，有时还执行一些 Flex 配方。

当您

require profiler-pack

时，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，这些软件包作为第一级依赖项安装，除非您将

--unpack

 标志传递给 

require

，或者在安装后执行 

unpack

。现在这些包默认解压，这更好，因为否则“真正的”依赖项隐藏在 Symfony“元包”后面。

安装后

profiler-pack

被移除是完全正常的行为。您不能保留该软件包，而且它也不会带来任何运行时功能。

您正在寻找的“调试”选项卡是由不同的包提供的，如评论中的

msg 所解释的那样。它由 symfony/debug-bundle 提供，您似乎已经安装了。尽管安装了，但它似乎不存在，您的安装可能由于某种原因而过时。

但更有可能的是，您的

bundles.php

文件中未启用该捆绑包。确保它在那里：

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