ruby - 为什么会出现未初始化常量 Stuff::HTTPParty 错误？

Question

我的系统上有 HTTParty gem，我可以在 Rails 中使用它。

现在我想单独使用它。

我正在尝试:

class Stuff
  include HTTParty
  def self.y
    HTTParty.get('http://www.google.com')
  end 
end
Stuff.y

但是我明白了

$ ruby test_httparty.rb 
test_httparty.rb:2:in `<class:Stuff>': uninitialized constant Stuff::HTTParty (NameError)
        from test_httparty.rb:1:in `<main>'

你必须要求'httpparty':

require 'httparty'

class Stuff
  include HTTParty
  # ...
end
