Gets.chomp不能正常工作

Question

我在做第11个练习了解Ruby的难法。我一定要得到这样的：通过写这

How old are you? 35 
How tall are you? 6'2" 
How much do you weigh? 180lbs 
So, you're 35 old, 6'2" tall and 180lbs heavy. 

：

print "How old are you? " 
age = gets.chomp() 
print "How tall are you? " 
height = gets.chomp() 
print "How much do you weigh? " 
weight = gets.chomp() 

puts "So, you're #{age} old, #{height} tall and #{weight} heavy." 

，但我得到这个：

How old are you? 
How tall are you? 
How much do you weigh? 
So, you're old, tall and heavy. 

这意味着，gets.chomp不工作，我不明白任何东西。

Answer 1

你应该输入值，而不仅仅是按回车键，当运行程序后，系统提示：

# ⇓ prompt ⇓ ⇓⇓ YOUR INPUT!!! 
How old are you? 35 

旁注：chomp后面的括号中是多余的，而不是红宝石地道。
