错误“无需处理元数据类”。当在Symfony（使用Doctrine）中生成DB表时，使用php app / console doctrine：generate：entity创建 [英] Error "No Metadata Classes to process." when generating DB tables in Symfony (using Doctrine) created using php app/console doctrine:generate:entity

问题描述

Symfony新手在这里！我安装了Symfony，我做了一个控制器和一个动作，一些HTML正确显示。所以，Symfony工作正常。我有一个问题在数据库中创建实体表。我创建了一些实体使用（注释和一些其他方式做出这些 - 我尝试了几种不同的方式通过控制台，实现相同的结果实体）。要创建我使用的实体：

  php app / console doctrine：generate：entity 
  
 
 
 
然后，当我尝试将其刷新到数据库（为了创建表），我使用这个命令：
  php app / console doctrine：schema：update --force 
  
运行该命令后，得到此错误，并且 - 正如我预期的 - 不创建表：
 
 
 
我尝试清除symfony缓存。
 
我检查AppBundle是在AppKernel中注册的。
 
我检查了在实体管理器中的自动映射设置为true。 
 
 
 
我在这里缺少什么？为了提醒你，我刚刚安装了一个新的Symfony，并执行了我上面描述的步骤。我感谢您的帮助，因为我真的需要这个，因为我想学习Symfony。
解决方案
我删除了整个bundle，控制台，然后通过控制台创建表，这一次它工作。我仍然不知道我以前的Symfony设置有什么问题。
 
Symfony newbie here! I installed Symfony and I made a controller and an action and some html is displayed properly. So, Symfony is working fine. I have a problem creating entity tables in the database. I created some entities using (annotations and some other way of making those - I tried couple of different ways of making entities through console, with same result). To create entities I used:
php app/console doctrine:generate:entity
And then, when I try to flush it to the database (in order to create the table(s)), I use this command:
php app/console doctrine:schema:update --force
After running that command, I get this error, and - just as I expected - the tables are not created:

I tried to clear the symfony cache.

I checked AppBundle is registered in AppKernel.

I checked that auto mapping is set to true in entity manager.  

What am I missing here? To remind you, I have just installed a fresh Symfony and did the steps I described above. I appreciate your help since I really need this because I want to learn Symfony.
解决方案
I deleted whole bundle, and created bundle through console, and then created tables through console, and this time it worked. I still don't know what was wrong with my previous setting(s) of Symfony.
