为什么作曲家更新需要访问数据库 [英] Why does a composer update need access to the database

问题描述

我正在使用Symfony 2.8，在启动一个简单的 composer update 命令时遇到了一些问题。

I am working with Symfony 2.8 and running into some issues launching a simple composer update command.

此错误来自我的开发环境。我正在使用无所事事的虚拟机。错误如下：

This error comes on my development environment. I am using a vagrant virtual machine. Here is the error:

[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，这是在主机上启动命令时发生的。 PHP无法连接到数据库，因为我的主机没有任何主机。因此，这是正常行为。

Of course, this is happening when I launch the command on my host machine. PHP cannot connect to the database because my host machine doesn't have any. So this is a normal behaviour.

当我SSH到VM中时，该命令运行良好。

The command works well when I ssh into my VM.

所以我可以在这里停止，然后从我的VM更新我的依赖项。

So I could stop here and just update my dependencies from my VM.

但是，我不希望 composer更新访问我的数据库，而且我不知道为什么它会需要它。

However, I don't want a composer update to access my database, and I don't see why it would need it.

我应该在哪里查看或我可以给您提供什么信息来帮助我解决问题？

Where should I look or what information could I give you to help me solve my problem?

推荐答案

自Doctrine 2.5起， Dctrine\DBAL\Connection :: detectDatabasePlatform（）会在许多命令上调用，并且会发出调用数据库（在此处发出： https://github.com/doctrine/dbal/issues/990 ）。

Since Doctrine 2.5, Dctrine\DBAL\Connection::detectDatabasePlatform() is called on many commands and will issue a call to the database (issue here: https://github.com/doctrine/dbal/issues/990).

解决方法是在Doctrine配置中设置数据库版本：

The workaround is to set DB version in Doctrine configuration:

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