为什么我在我的路线文件中出现这个错误？

Question

好的，我已经缩小了路径文件的错误。当我有devise_for：用户时，甚至在删除所有宝石并通过演练重新安装Devise之后。我得到耙db：migrate或rails s或任何rails命令，我得到以下错误。

如果我#devise_for我没有得到这个错误：用户

有人会说这是怎么回事呢？

让我知道如果你想别的贴，我想保持我的职位，需要什么，但这里是路线文件。

EvolvingFinal::Application.routes.draw do 
    devise_for :users 
    root to: 'pages#home' 
    resources :admins 
    resources :users 

    resources :books do 
    resources :snippets, :only => [:create, :edit, :update, :destroy] 
    end 

    post "books/:id/activate" => "books#approve", :as => "active_book" 
    post "snippets/:id/activate" => "snippets#approve", :as => "active_snippet" 
end 

Answer 1

Use gem 'devise', '3.0.0' 

您可能需要重新运行安装程序制定创业板已更新后。
