$PHP vendor/doctrine/orm/bin/doctrine orm:schema-tool:create --dump-sql

我得到了这个而不是预期的功能：

You are missing a "cli-config.PHP" or "config/cli-config.PHP" file in your
project,which is required to get the Doctrine Console working. You can use the
following sample as a template:

<?PHP
use Doctrine\ORM\Tools\Console\ConsoleRunner;

// replace with file to your own project bootstrap
require_once 'bootstrap.PHP';

// replace with mechanism to retrieve EntityManager in your app
$entityManager = GetEntityManager();

return ConsoleRunner::createHelperSet($entityManager);

问题：

>我在ZF2上,没有名为bootstrap.PHP的文件
>我是ZF2的新手,所以我不知道我的实体管理器是什么以及我应该为GetEntityManager放置什么

我该如何工作？
