设计无法检测：omniauthable，但它就在那里(Devise can't detect :omniauthable, but it's there)

 我有一个RoR应用程序，运行Devise Gem进行身份验证。 对于我的新API，我实现了Gem“devise-token-auth”： https ： //github.com/lynndylanhurley/devise_token_auth 
 
 由于我希望Devise运行网站和API身份验证，我也遵循以下说明中的额外提示（以及Gem's Git的常见问题解答）： http ： //www.developingandrails.com/2015/02/api -authentication与- devisetokenauth.html 
 
 我已停用Devise's：确认，但已激活：omniauthable。 一切似乎都已到位，但我收到以下错误： 
 
/Users/sebastianplasschaert/.rbenv/versions/2.2.1/lib/ruby/gems/2.2.0/gems/devise-3.5.2/lib/devise/rails/routes.rb:240:in `block in devise_for': Mapping omniauth_callbacks on a resource that is not omniauthable (ArgumentError)
Please add `devise :omniauthable` to the `User` model
 
 在我的用户模型中，我从以下代码开始： 
 
class User < ActiveRecord::Base


  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :invitable, :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable,
         :omniauthable
  include DeviseTokenAuth::Concerns::User
 
 所以，：omniauthable似乎在那里。 当我停用时： 
 
include DeviseTokenAuth::Concerns::User
 
 然后一切都有效（但我需要它用于我的API身份验证）。 
 
 关于我做错的任何想法？ 

I have a RoR application, running the Devise Gem for authentification. For my new API I've implemented the Gem "devise-token-auth": https://github.com/lynndylanhurley/devise_token_auth
 
Since I want Devise to run for the website and API authentication, I followed the extra tips in the following instruction as well (and als the FAQ of the Gem's Git): http://www.developingandrails.com/2015/02/api-authentication-with-devisetokenauth.html
 
I've deactivated Devise's :confirmable, but activated :omniauthable. Everything seems to be in place, but I'm getting the following error:
 
/Users/sebastianplasschaert/.rbenv/versions/2.2.1/lib/ruby/gems/2.2.0/gems/devise-3.5.2/lib/devise/rails/routes.rb:240:in `block in devise_for': Mapping omniauth_callbacks on a resource that is not omniauthable (ArgumentError)
Please add `devise :omniauthable` to the `User` model
 
And in my User model I start with the following code:
 
class User < ActiveRecord::Base


  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :invitable, :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable,
         :omniauthable
  include DeviseTokenAuth::Concerns::User
 
So, :omniauthable seems to be there. When I deactivate:
 
include DeviseTokenAuth::Concerns::User
 
then everything works again (but I need it for my API authentication).
 
Any ideas on what I'm doing wrong?
