Ruby中的簡單“需求”問題

Question

為了學習Ruby，我正在跟着《為什么要對Ruby進行嚴格訓練》，而當他在教程中首次引入'require'方法（？）時，我遇到了一些問題。

本質上，我制作了一個名為“ wordlist.rb”的文件，其中包含：

  code_words = {
  'starmonkeys' => 'Phil and Pete, those prickly chancellors of the New Reich',
  'catapult' => 'chucky go-go', 'firebomb' => 'Heat-Assisted Living',
  'Nigeria' => "Ny and Jerry's Dry Cleaning (with Donuts)",
  'Put the kabosh on' => 'Put the cable box on'
}

然后，我有另一個名為“ files.rb”的Ruby Scipt：

require 'wordlist'

#Get evil idea and swap in code words
print "Enter your new idea: "
idea = gets

#real will have the key and code will have the value
#Method followed by ! (like gsub!) are known as destructive methods
code_words.each do |real, code|
    safe_idea = idea.gsub!( real,code )
end

#Save the jibberish to a new file
print "File encoded. Please enter a name for this idea: "
idea_name  = gets.strip

File::open( "idea-" + idea_name + ".txt", "w") do |f|
    f 

When I try to run the Ruby script i get:

files.rb:9: undefined local variable or method `code_words' for main:Object (NameError)

任何想法如何使“要求”正常工作以引用單詞表？
