Question

我正在使用Symfony 2.8并遇到一些问题，启动一个简单的composer update命令。

此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，我不希望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()在许多命令上被调用，并将发出对数据库的调用（此处出现问题：https://github.com/doctrine/dbal/issues/990）。

解决方法是在Doctrine配置中设置数据库版本：

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