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

Question

当我跑 php -d memory_limit=2G ../composer/composer.phar 安装 ，我收到关于不存在的参数“database_driver”参数的错误。但是，如果我从我的 parameters.yml 和 parameters.yml.dist 文件中删除所有引用，那么我的网络应用程序将失败:

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 中定义了“database_driver”参数.yml 和 参数.yml.dist 文件，它存在于我的 中config.yml 文件。

**我需要更改什么才能成功运行“composer install”命令？

注意:我还看到“composer install”命令的以下输出表明我的 composer.lock 文件已过期并运行“composer update”命令，但是当我这样做时，它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 3 场内存和超过 28 场可用磁盘空间!如果可能，我想先尝试解决“database_driver”问题**

这是 的输出“堆肥器安装”命令，上面:

我通过添加 解决了这个问题数据库驱动程序 中的参数参数.yml 以及 参数.dist

我想每当我们更新 参数.yml (使用应该在 prod 服务器上的配置也很好)，您也必须更新文件参数 .yml.dist 。

以下是 的示例结构参数.yml.dist 文件

例如:

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