rake db: миграция отменяется при переносе гема

Я уверен, что это достаточно простая ошибка, я просто не могу понять это. Я устанавливаю ryanto/acts_as_votable gem и получаю следующую проблему. Есть похожие проблемы, но я не могу найти какие-либо исправления, которые могут быть реализованы до того, как rake db: migrate

Gemfile:

gem 'acts_as_votable', '~> 0.10.0'

тогда я

rails generate acts_as_votable:migration
rake db:migrate

Затем грабли прерываются, и я получаю это сообщение

Ваш файл маршрутов неверен.

Правильный код:

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

Я думаю, что проблема с вашим файлом маршрутов, вы добавили resources :posts вне Rails.application.routes.draw блок.

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

NoMethodError: неопределенный метод `resources'для main:Object

У тебя есть resources :posts за пределами block, Поместите это внутрь

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

Исправить я должен был пойти в db>migrate>'файл, который я мигрировал' и добавить

class AddMissingIndexes < ActiveRecord::Migration[4.2]
