Ruby - 意外的tIDENtifier，期待$結束

我剛開始學習Ruby。我正在創建一個簡單的程序，但我仍然不確定如何使用它。這是我的代碼：

=begin 
Filename: GameCompanyPoem.rb 
Program Name: Poem Generator 
Version 1.0 
Created: March 7th, 2013 
Purpose: To generate a poem based on key words given by the user 
=end 
print 'The following program will ask you to input words. Based on the words you input it will generate a poem. Now, please enter a name. ' 
name = gets.chomp 
print 'Please enter a mammal. ' 
mammal = gets.chomp 
print 'Now please enter a colour. ' 
colour1 = gets.chomp 
print 'We are almost done! Please enter a place or location now. ' 
place = gets.chomp 
print 'Now enter a verb. ' 
verb1 = gets.chomp 
print 'And another verb. ' 
verb2 = gets.chomp 
print 'Your poem will now be generated. Press enter to continue. 
space = gets.chomp 
print 'Someone by the name of ' + name + 'had a little' + mammal + ', little ' + mammal + ', little ' + mammal + ',' + name + 'had a little ' + mammal + 'its fleece was' + colour + 'as snow. It followed her to ' + place + 'one day, ' + place + 'one day, ' + place + 'one day, it made the children ' + verb1 + 'and ' + verb2 + 'to see a ' + mammal + 'at' + place + '."'

當我運行它，在最後的方法（打印），每一個空間都有這樣的錯誤：

意外tIDENtifier，期待$結束

在每一個空間，如果我填補它，然後就不見了，但它進入到下一格

閉引號上缺少''你的詩現在將產生。按enter鍵繼續。「語法突出顯示器使其更加明顯。 – 2013-03-07 18:20:17

並且在最後一個字符串末尾有一個額外的'''（雙引號）。請參閱我的回答以獲得完整修復 – BlackHatSamurai 2013-03-07 18:21:51

，它應該是coulor1，而不是顏色，就像@limelights提到的。 – BlackHatSamurai 2013-03-07 18:24:05

嘗試：

print 'Your poem will now be generated. Press enter to continue.' 
print 'Someone by the name of ' + name + 'had a little' + mammal + ', little ' + mammal + ', little ' + mammal + ',' + name + 'had a little ' + mammal + 'its fleece was' + colour1 + 'as snow. It followed her to ' + place + 'one day, ' + place + 'one day, ' + place + 'one day, it made the children ' + verb1 + 'and ' + verb2 + 'to see a ' + mammal + 'at' + place + '.'

另外，他錯過了變量'colour'，它應該是'colour1'！:) – 2013-03-07 18:22:40

好的接收！已添加。謝謝！ – BlackHatSamurai 2013-03-07 18:23:40

感謝您的幫助！我修正了顏色變量，發現我在某處丟失了一個撇號那裏:) – user2145566 2013-03-07 18:27:59

一個NIFT y在包括Ruby在內的很多語言中使用技巧插入

print "Someone by the name of #{name} had a little #{mammal}, little #{mammal}, little #{mammal}, had a little #{mammal} its fleece was #{colour} as snow. It followed her to #{place} one day, #{place} one day, #{place} one day, it made the children #{verb1} and #{verb2} to see a #{mammal} at #{place}."

嗯，它可能不會再押韻了。

還有一點。查看Ruby Interpolation瞭解詳細信息。但基本上ruby運行到＃{something}，它將其替換爲某個結果。

print "1 + 2 = #{1 + 2}"將打印

1 + 2 = 3
