Ruby on rails rake db:migrate在迁移gem时中止

我确信这是一个很简单的错误，我就是想不出来。 我正在安装ryanto/acts_as_votable gem，我遇到了以下问题。 也有类似的问题，但我找不到任何可以在rake db:migrate之前实现的修复

档案：

gem 'acts_as_votable', '~> 0.10.0'

那我就

rails generate acts_as_votable:migration
rake db:migrate

然后rake被中止，我收到了这个消息

新错误：

StandardError: An error has occurred, this and all later migrations  
anceled:

Directly inheriting from ActiveRecord::Migration is not supported. Please 
specify the Rails release the migration was written for:

  class ActsAsVotableMigration < ActiveRecord::Migration[4.2]

StandardError：发生了一个错误，此迁移和所有后续迁移都发生了错误
取消：
不支持直接从ActiveRecord:：Migration继承。请
指定为其编写迁移的Rails版本：
类ActsAsVotableMigration

您的路由文件不正确

正确代码：

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

---

我认为问题在于您的routes文件，您在

Rails.application.routes.draw

block之外添加了

resources:posts

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

NoMethodError:main:对象的未定义方法“资源”

您有

资源：在
块之外发布
。把它放进去

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

修复了我不得不转到db>migrate>“我正在迁移的文件”并添加

class AddMissingIndexes < ActiveRecord::Migration[4.2]

class AddMissingIndexes
请在此处添加您的路由文件。听起来您的gem希望您的ruby版本升级到2.3.1:
RubyDep:警告：您的ruby已过时/有缺陷。RubyDep：警告：您的Ruby是：2.3.0（buggy）。建议：升级到2.3.1。
请仔细阅读错误消息，这样您将拒绝回答。是否运行了
捆绑安装
？@LiffeyD更正您的路由文件。在街区外。查看我发布的回复感谢一百万我现在收到一个错误，说我需要说明它的编写版本，但我可以访问它，因为它不会迁移它。我会把信息写在上面的代码框中嗨，我用上面的代码修改了我的路由文件，谢谢。如果有帮助，这里有一个到我的c9.io的链接
class AddMissingIndexes < ActiveRecord::Migration[4.2]
