Use Watir in Shoes (ruby) - ruby

Question

I'm trying to do an application in ruby. I want to collect information from the user using some UI interface. Then use this info in my script to fill some form on a web page.
I use Shoes as UI
I use Watir as Browser "manager"
Here a simple sample of what i'm trying to do
Shoes.setup do
gem 'watir'
end
require 'watir'
Shoes.app do
stack do
edit_line do |e|
#url = e.text
end
button("Test"){
browser = Watir::Browser.new
browser.goto #url
#Do some stuff
}
end
end
But then When the application start it's trying to installing watir and freeze because of error:

Answer 1

The error says that rake requires rubygems >= 1.3.2
You either need to upgrade rubygems or downgrade rake to a version compatible with your current rubygems.
Edit: or specifiy a version of watir that will run with an older rubygems & rake

Answer 2

Shoes has this problem with many native gems, i advise you to try this with green shoes
['rubygems','green_shoes','watir'].each(&method(:require))
Shoes.app do
stack do
Watir::Browser.default = 'ie'
browser = Watir::Browser.new
browser.goto 'http://bit.ly/watir-example'
browser.text_field(:name => 'entry.0.single').set 'Watir'
browser.text_field(:name => 'entry.1.single').set "I come here from Australia. \n The weather is great here."
browser.radio(:value => 'Watir').set
browser.button(:name => 'submit').click
end
end
