我正在跟随'为什么是Ruby的尖锐指南'来学习Ruby，当他第一次在他的教程中介绍'require'方法（？）时遇到了一些问题。
基本上我创建了一个名为'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'
}
然后我有另一个名为'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)
知道如何让'require'正常工作以引用wordlist吗？
