我尝试设置我的 symfony 项目，一切都很好，因为我尝试创建学说数据库。 我在 .env 文件中写入了 DATABASE_URL，这是正确的，我想是这样，但是无论是我的本地 xampp 服务器还是我的 Web 服务器，都不起作用。

我总是遇到同样的错误：

[critical] Error thrown while running command "doctrine:database:create". Message: "An exception occurred in the driver: could not find driver"


In ExceptionConverter.php line 119:

  An exception occurred in the driver: could not find driver


In Exception.php line 30:

  could not find driver


In Driver.php line 28:

  could not find driver
