机械化Ruby 1.9.3编码问题

时间：2012-01-07 10:17:45

标签： ruby encoding rake mechanize mechanize-ruby

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!

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

或

gem 'mechanize', '2.0.1' and `bundle update`

我在2.1中遇到了同样的问题 顺便说一下，关于机械化github的讨论正在进行中
