ruby – Sinatra不是以twitter gem开头的

/var/lib/gems/1.9.1/gems/sinatra-1.4.4/lib/sinatra/base.rb:1488:in start_server’：HTTP的undefined methodrun’：模块(NoMethodError)

require 'sinatra/base'
require_relative "twt.rb"

class SinatraApp < Sinatra::Base
    set :static,true
    set :public_folder,File.dirname(__FILE__) + '/static'

    get '/getuserinfo' do
        @user = twit.getuserinfo
        erb :userInfo
    end
end

SinatraApp.run!

在“twt.rb”我需要推特(5.7.1)

require 'twitter'

class Twit
    attr_accessor :client

    def initialize(consumer_key,consumer_secret,access_token,access_token_secret)           
        @client = Twitter::REST::Client.new do |config|
          config.consumer_key        = consumer_key
          config.consumer_secret     = consumer_secret
          config.access_token        = access_token
          config.access_token_secret = access_token_secret
        end
    end

    def getUserInfo
        return user = {     
            "name"=> client.current_user.name,"id" => client.current_user.id
        }
    end

    def showAllFriends
         client.friends.each { |item| puts item.name }       
    end

    def showFollowers
        client.followers.each { |item| puts item.screen_name }
    end

    def showAllTweets       
         client.user_timeline.each {|item| puts item.text}
    end

    def showAllUserTweets(userScreenName)                   
         client.user_timeline(userScreenName).each {|item| puts item.text}
    end

    def sendTweet(content)
        client.update(content)
    end
end

如果我删除require_relative“twt.rb”行sinatra工作正常.
