itunes搜索红宝石:未初始化的常量Itunes

Question

使用这个itunes搜索 gem，文档看起来非常简单。它失败了

NameError:未初始化常量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

这是我的密码

$ 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

开发人员可能会更改模块名称或编写不正确的文档，正如您应该做的那样：

base = ItunesSearch::Base.new

而不是：

base = Itunes::Base.new

因为模块名为ItunesSearch，而不是Itunes。这应该有效:)
