我是第一个使用 ruby​​ 的人，所以当我遵循指南(http://guides.rubyonrails.org/getting_started.html)时，我收到了如下错误:

Started GET "/questions" for 127.0.0.1 at 2012-06-07 17:22:36 +0900

SyntaxError (/Users/sookcha/Desktop/Dev/CSap/app/models/question.rb:3: invalid multibyte char (US-ASCII) /Users/sookcha/Desktop/Dev/CSap/app/models/question.rb:3: syntax error, unexpected $end, expecting keyword_end   validates :name,  :presence => true ^): app/controllers/questions_controller.rb:2:in `'

当我刷新页面时，我收到以下不同的错误:

Started GET "/questions" for 127.0.0.1 at 2012-06-07 17:22:40 +0900

NoMethodError (undefined method `key?' for nil:NilClass):

我的代码是

class Question < ActiveRecord::Base
attr_accessible :content, :name, :title
validates :name,  :presence => true
validates :title, :presence => true,
                  :length => { :minimum => 5 }

end

我的代码有什么问题吗？

编辑

当我插入时 # encoding: utf-8,在我的代码中，我收到了一个不同的错误，例如:
/Users/sookcha/Desktop/Dev/CSap/app/models/question.rb:5: syntax error, unexpected tSYMBEG, expecting keyword_do or '{' or '(' validates :name, :presence => true ^ /Users/sookcha/Desktop/Dev/CSap/app/models/question.rb:7: syntax error, unexpected tASSOC, expecting keyword_end :length => { :minimum => 5 } ^):
怎么了？

有一个non-breaking space在您的代码中:

validates :name,  :presence => true
                ^
