Ruby中的简单“需求"问题 [英] Simple 'require' problem in Ruby

问题描述

为了学习Ruby，我正在跟着《为什么要对Ruby进行艰苦的指导》，而当他在本教程中首次引入'require'方法(?)时，我遇到了一些问题.

I'm following along with 'Why's Poignant Guide to Ruby' in order to learn Ruby and I am having some problem when he first introduces the 'require' method(?) in his tutorial.

基本上，我制作了一个名为'wordlist.rb'的文件，其中包含:

Essentially I make a file called 'wordlist.rb' which contains:

  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'
}

然后我有了另一个名为"files.rb"的红宝石密码:

I then have another ruby scipt called 'files.rb':

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 

当我尝试运行Ruby脚本时，我得到:

When I try to run the Ruby script i get:

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

是否知道如何使要求"正常工作以引用单词表?

Any idea how to get the 'require' to work properly to reference wordlist?

推荐答案

局部变量存在问题.您可以查看此处-解决方案存在完全相同的问题.

There is a problem with local variable. You can look here - there is exactly the same problem with a solution.
