我熟悉Symfony3，并且无法运行CRUD生成器。我的终端输出如下：
➜ keys php bin/console generate:doctrine:entity
Welcome to the Doctrine2 entity generator
This command helps you generate Doctrine2 entities.
First, you need to give the entity name you want to generate.
You must use the shortcut notation like AcmeBlogBundle:Post.
The Entity shortcut name: keys:passcodes
Bundle "keys" does not exist.
The Entity shortcut name:
➜ keys php bin/console generate:bundle --namespace=keys/Passcodes
Welcome to the Symfony bundle generator!
Are you planning on sharing this bundle across multiple applications? [no]:
Your application code must be written in bundles. This command helps
you generate them easily.
Give your bundle a descriptive name, like BlogBundle.
Bundle name [keys/Passcodes]:
The namespace must end with Bundle.
Bundle name [keys/Passcodes]: PasscodeBundle
Bundles are usually generated into the src/ directory. Unless you're
doing something custom, hit enter to keep this default!

What format do you want to use for your generated configuration?

Everything is OK! Now get to work :).

Instead of starting with a blank entity, you can add some fields now.
Note that the primary key will be added automatically (named id).
Available types: array, simple_array, json_array, object,
boolean, integer, smallint, bigint, string, text, datetime, datetimetz,
date, time, decimal, float, binary, blob, guid.
New field name (press <return> to stop adding fields): site
Field type [string]:

知道我做错了什么吗？如您所见，我引用并尝试了Symfony3 : Generate crud doesn't work
中的一些内容答案 0 :(得分：2)
在php中使用bin/console doctrine:generate:entity作为实体配置格式时，这似乎是一个问题。不幸的是，仅删除实体类并重新运行命令是不够的。由于这似乎是一个新项目，我建议从头开始：
symfony new keys
然后更新您的设置，例如parameters.yml中的数据库设置。您不必创建捆绑包，因为您可以将所有内容放入默认的AppBundle。
bin/console doctrine:generate:entity
> AppBundle:Passcode
然后选择annotation格式，并像之前一样输入所有字段要求。
现在你应该能够生成crud：
bin/console doctrine:generate:crud
> AppBundle:Passcode
您可以在这里使用您喜欢的任何配置格式。当您使用AppBundle时，您必须使用yml，因为这是当前格式，而生成器不喜欢混合样式。如果您有自己的捆绑包，则可以使用您喜欢的任何配置格式。
