我将Symfony 5.3.9与PHP 7.4.24和Composer 2.1.8一起使用。我想用markdown_html渲染以下模板，但我遇到了一个错误。
这是blog.html.twig
...
<article class="text-center">
{{ content | markdown_to_html }}
</article>
...
这就是我得到的错误：
在呈现模板的过程中引发异常("由于没有可用的markdown库，您无法使用">markdown_html"过滤器；尝试运行"composer require league/html to markdown_strong>"。")。
我运行CCD_ 1，但它说"；无需安装、更新或删除"；。
我的composer.json:

我已遵循此文档https://twig.symfony.com/doc/3.x/filters/markdown_to_html.html。我做错了什么？
解决方案是执行：
composer require league/commonmark
trick/markdown额外的包只提供了一个用于调用markdown处理器的trick扩展。您仍然需要安装一个实际的降价软件包。这在markdown_to_html页面的最后有点文档化，但不是很清楚。
如果没有找到降价包，则会发出html_to_markdown建议。如果这是需要的，那就好了，但markdown_to_html是一个更常见的需求。所有的评论都是这样。这个建议将在下一个版本中得到修正。
仅供参考，联赛套餐并不是唯一受支持的套餐。你也可以使用：
"require-dev": {
"erusev/parsedown": "^1.7",
"league/commonmark": "^1.0",
"league/html-to-markdown": "^4.8|^5.0",
"michelf/php-markdown": "^1.8"
如markdown extra/composer.json 中所列
