Symfony2 uglify CSS and JS

我正在尝试

php app/console asset:dump

来测试我的生产环境。我的css文件生成，但不是我的js文件。我有这个错误信息:

C:'wamp'www'projet>php app/console assetic:dump --env=prod --no-debug
Dumping all prod assets.
Debug mode is off.
09:48:02 [file+] C:/wamp/www/projet/app/../web/css/666.css

这是我的javascript块布局:

{% block javascripts %}
  {# jQuery depuis le CDN de Google, ou fallback sur une copie locale #}
    <script type="text/javascript" src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
    <script src="http://code.jquery.com/ui/1.10.4/jquery-ui.min.js"></script>
    {# Tous nos javascripts avec Assetic #}
  {% javascripts output='js/666.js' filter='?uglifyjs2' 
    'js/*.js' %}
    <script type="text/javascript" src="{{ asset_url }}"></script>
  {% endjavascripts %}
{% endblock %}

和我正在运行的css块:

{% block stylesheets %}
  {% stylesheets output='css/666.css' filter='?uglifycss'
    'css/*.css' %}
    <link rel="stylesheet" href="{{asset_url}}" type="text/css" />
  {% endstylesheets %}
{% endblock %}

在app.php中有这一行:

$kernel = new AppKernel('prod', false);

我的配置。yml:

# Assetic Configuration
assetic:
debug:          %kernel.debug%
use_controller: false
bundles:        [ ]
filters:
    uglifyjs2:
        bin: %kernel.root_dir%/Resources/node_modules/.bin/uglifyjs
    uglifycss:
        bin: %kernel.root_dir%/Resources/node_modules/.bin/uglifycss

我编辑我的代码使用uglify而不是YUI。但它比以前更糟糕，因为现在没有JS和CSS在prod中运行。
