在database_driver上获取[Symfony\Component\DependencyInjection\Exception\ParameterNotFoundException]错误

Question

当我运行php -d memory_limit = 2G ../composer/composer.phar install时,我收到有关不存在的参数"database_driver"参数的错误.但是,如果我从parameters.yml和parameters.yml.dist文件中删除所有引用,那么我的Web应用程序将失败:

ParameterNotFoundException in ParameterBag.php line 84:
You have requested a non-existent parameter "database_driver".
Did you mean one of these: "database_name", "database_user"?

所以我很清楚我需要这个参数.

我在我的parameters.yml和parameters.yml.dist文件中定义了"database_driver" ,它存在于我的config.yml文件中.

**为了成功运行'composer install命令,我需要更改什么？

注意:我还看到'composer install'命令的下面输出说我的composer.lock文件已经过时并且运行'composer update'命令,但是当我这样做时,它会因内存不足而失败错误,这是没有意义的,因为我在服务器上有三个内存,超过28演出的免费磁盘空间!如果可能的话,我想首先尝试解决"database_driver"问题**

以下是'composter install'命令的输出,如上所示:

我通过在parameter.yml和parameter.dist中添加database_driver参数解决了这个问题

我想每当我们更新parameters.yml（配置也应该在产品服务器上）时，您也必须更新文件parameters.yml.dist。

以下是parameter.yml.dist文件的示例结构

例子：

parameters:
    database_host: 127.0.0.1
    database_port: *****
    database_name: symfony
    database_user: root
    database_password: *****
    database_driver: mysql
