php - Symfony2 : InvalidArgumentException: The service definition "templating.helpers.assets" does not exist

Question

在处理我的 Symfony2 项目时，我(似乎)随机收到错误 InvalidArgumentException: The service definition "templating.helpers.assets"does not exist. 当我转到任何页面时。我试过回到早期的提交，但这并没有改变任何东西。所以它似乎不是我自己的源代码。我也无法 Composer 更新。我已尝试删除缓存、供应商目录和 composer.lock 文件，但我仍然收到此错误:

Loading composer repositories with package information

Updating dependencies (including require-dev)

Generating autoload files

Updating the "app/config/parameters.yml" file

[Symfony\Component\DependencyInjection\Exception\InvalidArgumentException]
The service definition "templating.helpers.assets" does not exist.

Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-update-cmd event terminated with an exception

[RuntimeException]
An error occurred when executing the "'cache:clear --no-warmup'" command.

有什么想法吗？

仅供引用服务 templating.helper.assets 存在

php app/console container:debug  templating.helper.assets 
[container] Information for service templating.helper.assets
Service Id       templating.helper.assets
Class            Symfony\Component\Templating\Helper\CoreAssetsHelper
Tags
    - templating.helper              (alias: assets)
Scope            request
Public           yes
Synthetic        no
Lazy             no
Synchronized     no
Abstract         no

它由 Symfony\Bundle\FrameworkBundle\FrameworkBundle() 创建并在 Resources\config\templating_php.xml

中定义

    <service id="templating.helper.assets" class="%templating.helper.assets.class%">
        <tag name="templating.helper" alias="assets" />
        <argument /> <!-- default package -->
        <argument type="collection" /> <!-- named packages -->
    </service>

所以将这个包添加到您的 appKernel.php

public function registerBundles()
{
    $bundles = array(
        //Standard
        new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
        //others bundles
