将SimpleCmsBundle添加到我现有的Symfony项目中

Question

对于一个客户我几乎完成了一个项目，在Symfony 2.8中构建。客户要求我添加一些额外的CMS功能，这样他就可以自己做一些基本的页面编辑，比如添加/编辑页面和菜单。

我不熟悉Symfony CMF，但正如我所知，只需安装SimpleCmsBundle即可。正如文档所声称的那样，它应该很容易安装，但我仍然会收到错误。以下是我采取的步骤：

• 将包添加到composer并在de kernel中实例化bundle。就像在http://symfony.com/doc/current/cmf/bundles/simple_cms/introduction.html#installation所说的一样。

• 正在运行composer update会产生以下错误：

  - doctrine/phpcr-bundle 1.3.4 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
  - doctrine/phpcr-bundle 1.3.3 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
  - doctrine/phpcr-bundle 1.3.2 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
  - doctrine/phpcr-bundle 1.3.1 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
  - doctrine/phpcr-bundle 1.3.0 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
  - doctrine/phpcr-bundle 1.2.4 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
  - doctrine/phpcr-bundle 1.2.3 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
  - doctrine/phpcr-bundle 1.2.2 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
  - doctrine/phpcr-bundle 1.2.1 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
  - doctrine/phpcr-bundle 1.2.0 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
  - doctrine/phpcr-bundle 1.1.2 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
  - doctrine/phpcr-bundle 1.1.1 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
  - doctrine/phpcr-bundle 1.1.0 requires phpcr/phpcr-implementation 2.1.* -> no matching package found.
  - symfony-cmf/simple-cms-bundle 1.3.0 requires doctrine/phpcr-bundle ~1.1 -> satisfiable by doctrine/phpcr-bundle[1.1.0, 1.1.1, 1.1.2, 1.2.0, 1.2.1, 1.2.2, 1.2.3, 1.2.4, 1.3.0, 1.3.1, 1.3.2, 1.3.3, 1.3.4].
  - Installation request for symfony-cmf/simple-cms-bundle 1.3.0 -> satisfiable by symfony-cmf/simple-cms-bundle[1.3.0].
  

• 经过一番搜索，我发现我错过了一个PHPCR实现：https://github.com/symfony-cmf/simple-cms-bundle/issues/142。所以我安装了jackalope/jackalope-doctrine-dbal

• 现在运行composer update会产生：

  You have requested a non-existent parameter "Could not determine the Doctrine manager. Either Doctrine is not configured or a bundle is misconfigured.".
  

现在我被卡住了，因为这个错误几乎没有给我谷歌的结果。显然，我是唯一一个遇到此错误的人。我做错了什么？
