Crawler错误期待关键字结束

Question

我正在发布一个具体问题。原始问题位于：https://stackoverflow.com/questions/23480242/nokogiri-problems-parsing-html?noredirect=1#comment36006044_23480242

我正在重新发布，因为这个爬虫是一个不同的，我认为修复很简单，即使我无法弄明白。我的抓取工具代码是：

module NoMoreRackCrawler
        class << self
                def noko_doc
                        Nokogiri::HTML(open('http://www.nomorerack.com/'))
                end

                def update
                        doc = self.noko_doc

                        doc.css('.deal').each do |deal|
                                title = deal.css('.display').css('p').children.text
                                deal_price = deal.css('.display').css('.pricing').css('ins').children.first.text.gsub("$","").to_f
                                retail_price = deal.css('.display').css('.pricing').css('del').children.first.text.gsub("$","").gsub(" Retail","").to_f
                                image_url = deal.css('img').first.attr('src')
                                url = "http://www.nomorerack.com#{deal.css('.image a').attribute('href').value}"

                                deal = Deal.where( title: title, source: "No More Rack" ).first_or_create
                                deal.category = "Deal Sites"
                                deal.deal_price = deal_price
                                deal.retail_price = retail_price
                                deal.image_url = image_url
                                deal.url = url
                                deal.save
                        end
                end
                        module Home
                        def self.update
                                doc = Nokogiri::HTML(open("http://www.nomorerack.com/daily_deals/category/home"))
                                NoMoreRackCrawler::update_for_doc( doc, "Home" )
                        end

        end
end

我收到第二个网址（http://www.nomorerack.com/daily_deals/category/home）阻止的错误。我的错误信息是：

SyntaxError: /webservices/crawler/app/crawlers/no_more_rack_crawler.rb:33: syntax error, unexpected end-of-input, expecting keyword_end
/webservices/crawler/lib/tasks/crawlers.rake:37:in `block (2 levels) in <top (required)>'

我的结局在那里，我甚至尝试删除并添加一个结束，看看是否修复它。任何想法与我可能愚蠢的语法错误？感谢您的帮助和建议。
