ruby语法错误，意外$ end，期待keyword_end

以下代码显示错误如下：

"ruby -KU -- 'C:\Users\Ishmael\My Documents\Aptana Studio 3 Workspace\Simple\FirstFile' C:/Users/Ishmael/My Documents/Aptana Studio 3 Workspace/Simple/FirstFile:55: syntax error, unexpected $end, expecting keyword_end" 

我搜索了额外的结尾和尾随’。但是徒劳无功，我仍然无法弄清楚为什么它不起作用！

 class Greeter attr_accessor :name def initialize(name="dudes") @name=name end def say_hi if @name.nil? puts "..." else if @name.respond_to?("each") @name.each do |name| puts "Hello #{name.capitalize}!" end else puts "Hi #{@name.capitalize}!" end end def say_bye if @name.nil? puts "..." else if @name.respond_to?("join") puts 'Goodbye #{@name.join(", ").capitalize}! Come back soon!' else puts "Bye #{@name.capitalize}!" end end end if __FILE__ == $0 greeter = Greeter.new greeter.say_hi greeter.say_bye greeter.name = "Ishmael" greeter.say_hi greeter.say_bye greeter.name = ["Albert", "Brenda", "Charles", "Dave", "Englebert"] greeter.say_hi greeter.say_bye greeter.name = nil greeter.say_hi greeter.say_bye end

它没有抱怨额外的end ，而是文件的过早结束，因为缺少end 。 在这种情况下，您忘记在if __FILE__ == $0部分之前关闭课程。

这可能是因为你将elsif与else if混淆了，后者创建了一个全新的if块。
