`gets`not工作，如果... end`statement

Question

我想找到我的劇本要等到用戶點擊回車鍵時使用if...end

input = 3 

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

這並不方式工作，我得到

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

我應該怎麼用，而不是gets暫停腳本？

謝謝你的時間

Answer 1

嘗試更換gets與$stdin.gets

Answer 2

它爲我工作，你確定你想從控制檯讀取？

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
