`gets`not工作，如果... end`statement

Question

我想找到我的剧本要等到用户点击回车键时使用if...end

input = 3 

if input > 2  
    puts "input is greater than 2" 
    gets 
    puts "this shouldn't appear before I type ENTER" 
end 

这并不方式工作，我得到

$input is greater than 2 
$this shouldn't appear before I type ENTER 

我应该怎么用，而不是gets暂停脚本？

谢谢你的时间

Answer 1

尝试更换gets与$stdin.gets

Answer 2

它为我工作，你确定你想从控制台读取？

input = 3 

if input > 2  
    puts "input is greater than 2" 
    puts "please enter your name" 
    name = gets 
    puts "hi #{name} this shouldn't appear before I type ENTER" 
end 

O/P

~/Desktop$ ruby demo.rb 
input is greater than 2 
please enter your name 
salil 
hi salil 
this shouldn't appear before I type ENTER
