symfony/profiler-pack 在安装后立即被删除

Question

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

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

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

为什么symfony/profiler-pack 在安装后立即被删除？

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 包是“元包”，安装后它们总是被“删除”

他们唯一的目的就是同时安装一堆一级相关的依赖，有时还会执行一些flex recipe。

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

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

你可以检查确认这个on packagist。

或者例如，如果您安装orm-pack，您将在第一级安装这些（例如，这些现在是您的项目的依赖项，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",

在过去，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，或者您在安装后执行unpack。现在这些包默认解包，这样更好，因为否则“真正的”依赖项隐藏在 Symfony“元包”后面。

profiler-pack 在安装后被删除是完全正常的行为。你不能保留那个包，它也不会带来任何运行时特性。

如msg in the comments 所述，您正在寻找的“调试”选项卡由不同的软件包提供。它由symfony/debug-bundle 提供，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而过时。

但更有可能的是，您的 bundles.php 文件中未启用捆绑包。确保它在那里：

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