unable to start webrick in windows xp

Question

i got this error while i try to start the webrick server on my windows xp.

←[31mCould not find eventmachine-0.12.10 in any of the sources←[0m
←[33mRun `bundle install` to install missing gems.←[0m

I've already did a 'bundle install'. Also tried to install mongrel but it's not helping!

Gemfile codes:

source 'http://rubygems.org'

gem 'rails', '3.0.10'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

#gem 'sqlite3'

group :production do
  gem 'pg'
end
group :development, :test do
  gem 'sqlite3'
end

gem 'thin'

# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger (ruby-debug for Ruby 1.8.7+, ruby-debug19 for Ruby 1.9.2+)
# gem 'ruby-debug'
# gem 'ruby-debug19', :require => 'ruby-debug'

# Bundle the extra gems:
# gem 'bj'
# gem 'nokogiri'
# gem 'sqlite3-ruby', :require => 'sqlite3'
# gem 'aws-s3', :require => 'aws/s3'

# Bundle gems for the local environment. Make sure to
# put test-only gems in this group so their generators
# and rake tasks are available in development mode:
# group :development, :test do
#   gem 'webrat'
# end

Try running these commands and then try rails s again.

gem install specific_install
gem specific_install -l http://github.com/eventmachine/eventmachine.git
