我尝试使用 php composer.phar update 在 symfony2 中更新我的供应商包，但是当我这样做时，我在此行之后收到一个错误：

更新“app/config/parameters.yml”文件

我得到的错误是：

[Symfony\Component\Config\Definition\Exception\InvalidConfigurationException]           
The child node "key" at path "security.firewalls.main.remember_me" must be configured. 

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. 

我的 security.yml 文件在其防火墙部分具有以下内容：

firewalls:
    main:
        pattern: ^/
        provider: fos_userbundle
        form_login:
