使用本教程，我正在尝试启动并运行 Symfony2 CMF。我能够启动框架，但没有加载任何样式或脚本。我收到了 js 和 css 的错误：

这些样式和脚本是从skeleton.html.twig 加载的：
{% stylesheets
...
<link rel="stylesheet" href="{{ asset_url }}" media="screen" type="text/css"/>
{% endstylesheets %}
和
{% block bottom_scripts %}
{% render(controller("cmf_create.jsloader.controller:includeJSFilesAction", { "editor": "ckeditor", "_locale": app.request.locale })) %}
{% endblock %}
从教程中，这些样式应该可以正常加载。我也在这里使用了 CMF 文档，并且可以加载样式，但是在文档中遇到了很多其他问题。也许我需要在我的 config.yml 中调整一些东西？
更新
这似乎是资产的问题。如果我手动将样式加载到skeleton.html.twig 中，它们就会出现。
有什么理由为什么资产会导致这种 MIME 类型转移？在这个庞大的框架中我没有正确的一些设置？
