iTunes搜索紅寶石：未初始化的常量Itunes

Question

使用此itunes search寶石，並且文檔看起來非常簡單。它失敗 與

NameError: uninitialized constant Itunes

gem install itunes-search 

Usage 

base = Itunes::Base.new 

search_object = base.search("term"=>"The Killers") 

# get an array of the search_objects 

results = search_object.results 

results.each do |result| 
    puts result.trackViewUrl 
end 

puts result.attributes 

這裏是我的代碼

$ irb 
irb(main):001:0> require 'rubygems' 
=> true 
irb(main):002:0> require 'itunes-search' 
=> true 
irb(main):003:0> base = Itunes::Base.new 
NameError: uninitialized constant Itunes 
from (irb):3 

Answer 1

的開發人員可能更改模塊名稱或書面的不正確的文件，你應該做的：

base = ItunesSearch::Base.new 

代替作者：

base = Itunes::Base.new 

因爲該模塊名稱爲ItunesSearch而不是Itunes。這應該工作:)
