即使使用寶石，Ruby'未初始化常量'錯誤

Question

我正在嘗試在我正在使用的紅寶石項目中使用Ankusa（https://github.com/livingsocial/ankusa）gem。

我運行下面的代碼安裝了ankusa寶石，但我仍然得到一個錯誤： 未初始化的常量Ankusa :: MemoryStorage（NameError）

require 'rubygems' 
require 'ankusa' 
require 'ankusa/hbase_storage' 

storage = Ankusa::MemoryStorage.new 
c = Ankusa::NaiveBayesClassifier.new storage 

c.train :spam, "This is some spammy text" 
c.train :good, "This is not the bad stuff" 

puts c.classify "This is some spammy text" 

puts c.classifications "This is some spammy text" 

puts c.log_likelihoods "This is some spammy text" 

puts c.classnames 
storage.close 

任何幫助將不勝感激。

Answer 1

查看gem文件夾中的ankusa.rb。它只需要以下條件：

require 'ankusa/version' 
require 'ankusa/extensions' 
require 'ankusa/classifier' 
require 'ankusa/naive_bayes' 
require 'ankusa/kl_divergence' 
require 'ankusa/hasher' 

所以，你可能需要需要它明確

require 'ankusa/memory_storage'
