使用循环DO在方法中创建文本菜单

Question

我真的是Ruby中的新手。

所以我确实在循环中制作了一个菜单，它将我发送到" start.menu_one"，但是我可以在" def菜单_one"中进行另一个循环，可以将我发送到" def Menu_three"

问题是我无法运行代码吗？你们中的任何一个都知道问题是什么，因为我找不到。

file = File.new(".txt", "a")

class Start
  def menu_one 
    while (select !=2)  
    puts "Press 1 to make a new test"
    puts "Press 2 to search after test results"
    if (select == 1)
      start.menu_three
      break
    elsif (select == 2) # its here the problem is? 
    end
  def menu_two
    puts "Press 1 to see the overview of the tests"
  end
end
  def menu_three
    puts "hej"
  end
end 
  start = Start.new
  require 'io/console'
  select = 0

  puts "Welcome to the multiple choice test"
  while (select !=3)
    puts "Press 1 to login as admin"
      puts "n"
    puts "Press 2 to login as student"
      puts "n"
    puts "Press 3 to exit "
      puts "n"
    select = STDIN.getch.to_i 
    if (select == 1)
    start.menu_one
    break
  elsif (select == 2)
    start.menu_two
    break 
  elsif (select == 3)
    puts "You have now exited the program"
    abort
  end
end 
end
