Subject: [ruby-dev:34882] Hpricotでエラー

るびきちです。

Ruby 1.8.7だと、外部ライブラリですがHpricotでエラーになります。

require 'rubygems'
require 'hpricot'
require 'open-uri'
RUBY_VERSION                    # => "1.8.6"
RUBY_RELEASE_DATE               # => "2008-03-03"
puts Hpricot(URI("http://d.hatena.ne.jp/rubikitch/").read)/"div.body"
# >> <div class="body">
# snip
# >> </div>


vs


require 'rubygems'
require 'hpricot'
require 'open-uri'
RUBY_VERSION                    # => "1.8.7"
RUBY_RELEASE_DATE               # => "2008-05-26"
puts Hpricot(URI("http://d.hatena.ne.jp/rubikitch/").read)/"div.body"
