I just started to work into symfony framework. I created an starting app with symfony and wanted to install bootstrap 3.3.5 with it. Bit I figured out that it is not working as expected. As the next step I installed Leafo Less.php. To add support for bootstrap > 3.2 I installed oyejorge/less.php with wrapper for the leafo lessc compiler.
I registered it in config.yml with the following lines:
assetic:
debug: "%kernel.debug%"
use_controller: false
bundles: [ ]
#java: /usr/bin/java
filters:
lessphp:
file: %kernel.root_dir%/../src/HomeBundle/Assets/Filter/lessc.php
apply_to: "\.less$"
# Formatter options: compressed, lessjs, classic
formatter: "compressed"
preserve_comments: false
cssrewrite: ~
so far the commands work. Next step was, according to the explanations at http://isometriks.com/using-less-with-symfony2 telling me I need to references the style sheet. So I added into the template the content:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>{% block title %}Welcome!{% endblock %}</title>
{% block stylesheets %}{% endblock %}
<link rel="icon" type="image/x-icon" href="{{ asset('favicon.ico') }}" />
{% stylesheets '@HomeBundle/Resources/less/bootstrap.less' %}
<link rel="stylesheet" href="{{ asset_url }}">
{% endstylesheets %}
</head>
<body>
{% block body %}{% endblock %}
{% block javascripts %}{% endblock %}
</body>
</html>
Everytime that I call the controller I get the message:
An exception has been thrown during the rendering of a template ("Unable to generate a URL for the named route "_assetic_5bb3373_0" as such route does not exist.") in base.twig at line 8.
Don't know what I'm doing wrong. Where is my mistake? Any help is appreceated.

使用Assetic时，您需要使用＆＃34; app / console assetic：dump＆＃34;命令生成css / less / js文件。这也将它们复制到Web文件夹以使其可访问。
调用此命令后，请检查web / css文件夹以查看编译的less是否在那里。
如果您没有在开发环境中运行（使用网址中的app_dev.php），则需要在运行命令时指定生产环境＆＃34; app / console assetic：dump --env = prod＆＃ 34;
