新手求助ruby问题

class Person
def name
@name
end

def gender
@gender
end

def age
@age
end
end

people = Person.new('Tom', 'male', 15)
puts people.name
puts people.gender
puts people.age

错误提示G:/RubyTest/person.rb:26:in `initialize': wrong number of arguments (3 for 0) (ArgumentError)
from G:/RubyTest/person.rb:26:in `new'
from G:/RubyTest/person.rb:26

这样的问题还是好好找本书看看吧！。这个帖子肯定是要被隐的
