作曲家需要 symfony/assets 安装

Question

我对 pimcore 比较陌生，很难获得合适的作曲家包。

首先我安装了pimcore

composer create-project pimcore/skeleton my-project

我将 TWIG 添加到项目中，因为它被推荐用于 symfony。 --> 所以我可以使用资产功能。 Symfony Asset

现在要包含文件，我想使用symfony的资产功能。但遗憾的是，“asset()”目前 return 没有任何路径。

{# the image lives at "public/images/logo.png" #}
<img src="{{ asset('images/logo.png') }}" alt="Symfony!"/>

所以我意识到，我必须安装资产包。但是每当我尝试添加要求时，我都会收到错误消息。我不确定是否需要将要求放在 pimcore 项目的 composer.json 文件中，或者放在 symfony/symfony 包的 composer.json 文件中。尽管如此，我在这两种情况下都会出错：

结果更新composer.json在项目根

  Your requirements could not be resolved to an installable set of packages.

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

symfony 包 (/vendor/symfony/symfony) 的结果更新 composer.json - 但我认为这是错误的

    Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for symfony/symfony No version set (parsed as 1.0.0) -> satisfiable by symfony/symfony[No version set (parsed as 1.0.0)].
    - don't install symfony/asset 5.x-dev|remove symfony/symfony No version set (parsed as 1.0.0)
    - Installation request for symfony/asset 5.x-dev -> satisfiable by symfony/asset[5.x-dev].


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

抱歉这个愚蠢的问题。谢谢你帮助我。

这是我使用的命令：

composer require symfony/asset

Answer 1

终于到了有趣的地步：正如错误消息告诉您的那样，symfony/symfony 已经安装（因为这是 pimcore/pimcore 的依赖项）。这个核心包包含 Symfony 的所有组件，安装一个单独的附加组件（如 symfony/asset）是不可能的。

如果您可以使用发布的图像标签 (<img src="{{ asset('images/logo.png') }}" alt="Symfony!"/>) 而不会在渲染过程中弹出任何错误消息（就：可以生成标记，即使图像的源未按预期生成），这也意味着安装了 asset 功能所需的 Twig 扩展。

因此，您的下一步是搜索缺少的资产配置以生成正确的图像 URL。
