我想找到一种方法让我的脚本等到用户点击 ENTER，同时使用if...end

input = 3

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

这不起作用，因为我得到

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

我应该用什么代替gets暂停脚本？

感谢您的时间

尝试替换gets为$stdin.gets

它对我有用，您确定要从控制台读取吗？

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
