我们使用postgres数据库对Web应用程序进行逆向工程.我们想使用symfony框架重构代码,但是我们在使用数据库时遇到了问题.

 目前,我们的项目正在使用MySQL数据库,只是对使用的表使用相同的结构.问题是,现在,我们需要使用postgresql数据库,因为有很多数据,据我们所知,它并没有真正适应MysqL.

我们进行了大量的研究,但是我们没有成功在symfony项目中创建postgresql数据库.
首先,我们尝试应用本教程：http://www.tutodidacte.com/symfony2-utiliser-une-base-de-donnee-postgresql我们尽可能地为我们的项目调整它.
这是我们的config.yml

但是当我们启动这个命令时：PHP bin / console doctrine：database：create –connection = pgsql我们得到了这个答案：

  [Doctrine\DBAL\Exception\DriverException]              
    An exception occured in driver: could not find driver  
  [Doctrine\DBAL\Driver\PDOException]  
   could not find driver
