您的HTML示例与显示的代码不匹配，加上您提供的URL已不存在，因此很难为您提供帮助

这是一个开始：

require 'nokogiri'

html = '<div class="zg_usedPrice">
    <a href="http://rads.stackoverflow.com/amzn/click/B000O3GCFU">52&nbsp;new</a>
    </div>
'
doc = Nokogiri::HTML(html)

text = doc.at('div.zg_usedPrice a').text # => "52\u00A0new"
text.gsub(/\u00A0/, ' ') # => "52 new"

需要“nokogiri”
html='1〕
'
doc=Nokogiri:：HTML（HTML）
text=doc.at（'div.zg_usedPrice a'）。text=>“52\u00A0new”
text.gsub（/\u00A0/，''）#=>“52新”

您能提供完整的错误跟踪吗？@Babai好的，我添加了它。请参阅我的编辑。第179行和第183行是什么？@Babai行179:`product_hash[：product]product_asin，`@Babai行183`：used_status=>product_used_price_status`
