机械化Ruby 1.9.3编码问题
使用以下代码（来自Mechanize站点，但在rake任务中）..
namespace :ans do task :grab => :environment do a = Mechanize.new { |agent| agent.user_agent_alias = 'Mac Safari' } begin a.get('http://google.com/') do |page| search_result = page.form_with(:name => 'f') do |search| search.q = 'Hello world' end.submit search_result.links.each do |link| puts link.text end end end end end 我收到编码错误..
rake aborted! "\x8B" from ASCII-8BIT to UTF-8
这是在使用以下内容时：

只需安装以前的机械化版本：
gem install mechanize -v 2.0.1
要么
gem 'mechanize', '2.0.1' and `bundle update`
我一直在用2.1 btw获得同样的问题，关于机械化github正在进行讨论
