为什么作曲家更新需要访问数据库

Question

我正在使用Symfony 2.8并遇到一些启动简单composer update命令的问题.

这个错误出现在我的开发环境中.我正在使用流浪汉虚拟机.这是错误:

[Doctrine\DBAL\Exception\ConnectionException]                              
  An exception occured in driver: SQLSTATE[HY000] [2002] Connection refused  



      [Doctrine\DBAL\Driver\PDOException]        
      SQLSTATE[HY000] [2002] Connection refused  



      [PDOException]                             
      SQLSTATE[HY000] [2002] Connection refused  


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

当然,当我在主机上启动命令时会发生这种情况.PHP无法连接到数据库,因为我的主机没有任何连接.所以这是一种正常的行为.

当我进入我的虚拟机时,该命令运行良好.

所以我可以在这里停下来,只是从我的VM更新我的依赖项.

但是,我不想composer update访问我的数据库,我不明白它为什么需要它.

我应该在哪里查看,或者我可以提供哪些信息来帮助我解决问题？

编辑:这是我的composer.json文件:

自Doctrine 2.5以来,Dctrine\DBAL\Connection::detectDatabasePlatform()在许多命令上调用它并将发出对数据库的调用(问题在这里:https://github.com/doctrine/dbal/issues/990).

解决方法是在Doctrine配置中设置DB版本:

doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                server_version: 5.6
