試圖取消網頁與角度來說，Hpricot在Ruby 1.9的時候我得到以下編碼錯誤：編碼問題角度來說，Hpricot
Encoding::CompatibilityError: incompatible character encodings: ASCII-8BIT and UTF-8
我可以做重現錯誤以下：

我得到了它與引入nokogiri工作。 – Sam 2010-07-06 10:01:47
就我個人而言，我推薦使用Hokrici的Nokogiri，因爲我的問題少得多。 – 2010-07-06 16:23:14
Nokogiri是hpricot的'drop in'替代品，我建議使用它，而不是由_why維護hpricot。 – 2010-08-29 22:18:35
