Cannot require 'nokogiri' in Rails (but works in irb)

Question

I\'ve just started using Ruby on Rails and so far it\'s working nicely. I\'m now trying to implement a gem but it\'s not working, and I am hoping it\'s just a beginner mistake -

Firstly try changing your controller to be somthing like

class HomeController < ApplicationController
    require 'nokogiri'
    require 'open-uri'

    def index
        url = "http://www.walmart.com/search/search-ng.do?search_constraint=0&ic=48_0&search_query=batman&Find.x=0&Find.y=0&Find=Find"
        doc = Nokogiri::HTML(open(url))
        @mattVar = doc.at_css("title").text
    end
end

I'm guessing you are also using bundler, check that you have include this gem and run bundle install.
