我确定这是一个足够简单的错误，我只是想不通。我正在安装 ryanto/acts_as_votable gem，我遇到了以下问题。有类似的问题，但我找不到任何可以在 rake db:migrate 之前实现的修复

宝石文件：

gem 'acts_as_votable', '~> 0.10.0'

那我是

rails generate acts_as_votable:migration
rake db:migrate

然后耙子被中止，我收到了这条消息

davemc:~/workspace/newsroom (rating) $ rake db:migrate

您的路线文件不正确。

正确代码：

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

我认为问题出在您的路线文件上，您已在块resources :posts之外添加。Rails.application.routes.draw

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

NoMethodError：main:Object 的未定义方法“资源”

你有resources :posts外面的block。把那个放在里面

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

修复我必须去 db>migrate>'file i was migrate' 并添加

class AddMissingIndexes < ActiveRecord::Migration[4.2]
