Gets.chomp不能正常工作

Question

我在做第11個練習瞭解Ruby的難法。我一定要得到這樣的：通過寫這

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." 

，但我得到這個：

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

這意味着，gets.chomp不工作，我不明白任何東西。

Answer 1

你應該輸入值，而不僅僅是按回車鍵，當運行程序後，系統提示：

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

旁註：chomp後面的括號中是多餘的，而不是紅寶石地道。
