初学ruby 怎么把一个类导入呢

[SambaGao]

1. 例如在

Person.rb 中

class Person
  def talk
    puts "nihao"
  end
  
end

Student.rb

class Student < Person
  def talk
    puts "nihao"
  end
  
end


p = Student.new

p.talk

结果
>ruby Student.rb
Student.rb:1: uninitialized constant Person (NameError)
>Exit code: 1

哈，是Python还是Ruby啊?

ruby不会自动到当前路径去找类的，要自己加。

require 'Person'

自己添加require上去就行了～～～不过发现csdn ruby on rails 貌似人不多阿～～

不用那么麻烦的，在ruby中，include就可以实现继承

class Student
  include Person
  def talk
    puts "nihao"
  end
  
end
