rake db：遷移gem時遷移被中止

-1

確定這是一個足夠簡單的錯誤，我只是無法弄清楚。我正在安裝ryanto/acts_as_votable gem，並且出現以下問題。有類似的問題，但我不能找到可以耙分貝之前執行任何修復：遷移rake db：遷移gem時遷移被中止

的Gemfile：

gem 'acts_as_votable', '~> 0.10.0'

那麼我

rails generate acts_as_votable:migration 
rake db:migrate

然後耙是中止，我收到此消息

請將您的路線在這裏提交。 –

這聽起來像是你的寶石想把你的ruby版本升級到2.3.1：'RubyDep：警告：你的Ruby已經過時了/ buggy。 RubyDep：警告：您的Ruby是：2.3.0（越野車）。建議：升級到 2.3.1.' – Jaeger

請仔細閱讀錯誤消息，以便您能答覆。 –

你的路線文件不正確。

正確的代碼：

感謝一百萬我現在得到一個錯誤，說我需要說明它的編寫版本，但我可以訪問它，因爲它不會遷移它。我會在 – LiffeyD

我認爲這個問題是你的路由文件，您已經添加resources :posts外Rails.application.routes.draw塊。

MyAppName::Application.routes.draw do 
    #resources 
end

以上的代碼框中轉發消息嗨，我修改了我的路由文件，上面的代碼，謝謝。 – LiffeyD

這是我的c9.io的鏈接，如果它有助於https://ide.c9.io/davemc/project-paperclip – LiffeyD

NoMethodError: undefined method `resources' for main:Object

你有resources :posts外block的。把裏面

Rails.application.routes.draw do 
    devise_for :users 
    root to: "posts#index" 
    resources :posts 
end
