需要在控制器

Question

gem install rubyoverflow 
irb 
> require 'rubyoverflow' 
=> true 

但其他模塊：

require 'rubyoverflow' 
include Rubyoverflow 

class QuestionsController < ApplicationController 
    def question_by_tag 
     ruby_q = Questions.retrieve_by_tag('ruby') 

得到錯誤：

LoadError in QuestionsController#question_by_tag no such file to load -- rubyoverflow

Rails.root: D:/artefacts/dev/projects/stack

app/controllers/questions_controller.rb:1:in `'

This error occurred while loading the following files: rubyoverflow

有控制器要導入爲模的任何特殊規則？

Answer 1

爲什麼你同時使用require和include？ include Rubyoverflow將足以

UPD

創業板，你應該把它添加到您的Gemfile（Rails的3.X）或config/environment.rb（Rails的2.X）

# Gemfile 
gem "rubyoverflow" 
# environment.rb 
config.gem "rubyoverflow" 

然後運行bundle爲Rails 3.x和rake gems:install for Rails 2.x
