你application_helper.rb好像坏掉了 你可能想要这样的东西：

module ApplicationHelper

  def full_title(page_title)
    base_title = "Ruby on Rails Tutorial Sample App"
    if page_title.empty?
      base_title
    else
      "#{base_title} | #{page_title}"
    end
  end

end

似乎module线路丢失了。这就是为什么 Ruby 抱怨end最后一行有一个额外的内容。
