Symfony 2 Assetic致命错误:在资产转储上找不到类'Assetic\Util\PathUtils‘

Question

我在Assetic上使用Symfony版本2.1.10，在上次的composer更新之后，我在尝试运行php app/console assetic:dump时得到以下错误

Dumping all dev assets.
Debug mode is on.
Fatal error: Class 'Assetic\Util\PathUtils' not found in /vendor/symfony/assetic-bundle/Symfony/Bundle/AsseticBundle/Command/DumpCommand.php on line 216

我不知道这里出了什么问题。我检查了Assetic和Symfony 2的GitHub问题页面，但找不到任何信息...

config.yml：

# Assetic Configuration
assetic:
    debug:          "%kernel.debug%"
    use_controller: false
    bundles:        ['FOSUserBundle', 'vaamoLandingPageBundle']
    #java: /usr/bin/java
    filters:
        cssrewrite: ~
        #closure:
        #    jar: "%kernel.root_dir%/Resources/java/compiler.jar"
        #yui_css:
        #    jar: "%kernel.root_dir%/Resources/java/yuicompressor-2.4.7.jar"

composer.js：

"require": {
        "php": ">=5.3.3",
        "symfony/symfony": "2.1.*",
        "doctrine/orm": ">=2.2.3,<2.4-dev",
        "doctrine/doctrine-bundle": "1.1.*",
        "twig/extensions": "1.0.*@dev",
        "symfony/assetic-bundle": "2.1.*",
        ...
    },

Answer 1

变化

"symfony/assetic-bundle": "2.1.*"

至

"symfony/assetic-bundle": "2.3.*"

比起它应该起的作用
