在 database_driver 上出现 [Symfony\Component\DependencyInjection\Exception\ParameterNotFoundException] 错误

Question

当我运行 php -d memory_limit=2G ../composer/composer.phar install 时，我收到关于不存在的参数“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 应用程序将失败并显示：

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。

**为了成功运行 'composer install 命令，我需要进行哪些更改？

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，它会失败并显示内存不足错误，这没有意义，因为我在服务器上有 3 GB 的内存和超过 28 GB 的可用磁盘空间！如果可能，我想先尝试解决“database_driver”问题**

这是上面 'composter install' 命令的输出：

我已经通过在 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 prod 服务器上）时，您也必须更新文件参数 .yml.dist。

以下是 parameter.yml.dist 文件的示例结构

示例：

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