未知函数“资产”-Symfony 3

Question

我将项目从 Symfony 2.8迁移到了3.4.20 ，但似乎根本没有发现资产问题。

我不断收到消息：

  

您是否忘记运行“ composer require symfony / asset”？未知函数“资产”。

我已经安装了symfony / asset，但这没有任何改变。

这是我的 config.yml

framework:
    templating:
        engines: ['twig']
    assets: ~

twig:
    debug:            "%kernel.debug%"
    strict_variables: "%kernel.debug%"

assetic:
    debug:          "%kernel.debug%"
    use_controller: "%kernel.debug%"
    bundles:
        - FOSUserBundle
        - MobiliteMainBundle
        - MobiliteUserBundle
    filters:
        cssrewrite: ~
    twig:
        functions:
            cssrewrite: ~

这是composer.json

这就是我加载CSS的方式

{% block stylesheets %}
    {% stylesheets
        '@MobiliteMainBundle/Resources/public/css/bootstrap.min.css'
        '@MobiliteMainBundle/Resources/public/css/bootstrap-theme.min.css'
        '@MobiliteMainBundle/Resources/public/css/jquery-ui-1.10.4.custom.min.css'
        '@MobiliteMainBundle/Resources/public/css/bootstrap-glyphicons.css'
        '@MobiliteMainBundle/Resources/public/css/global.css'
        '@MobiliteMainBundle/Resources/public/css/Desktop/select/select2.min.css'
        filter='cssrewrite' %}
        <link rel="stylesheet" href="{{ asset_url }}" />
    {% endstylesheets %}
{% endblock %}
