无法加载此类文件-pty（LoadError）

Question

Completely new to Ruby on Rails. My environment is Windows 2008 R2, and I just use the RailsInstaller to set it up. I was given a website, so I placed it under C:\\Sites. I followed the guide, and installed rails, as you can see the version down there in the code. Then I ran "rails server" to try to start the service, but I was given error message about "therubyracer-heroku-0.8.1.pre3 not installed, so I did a gem install and bundle install after that. Then therubyracer-heroku threw bunch of error, so I looked that up, told me I need to wrap it in a group, which I did and removed from production group within the gem file. Now when I do a "bundle install" everything is good, so I proceed with "rails server" and I got the error message down below. Any help ? please

source 'https://rubygems.org'
ruby '1.9.3'

gem 'rails', '3.2.13'

gem 'pg'
gem 'hashie'
gem 'figaro' # handles app configurations
gem 'airbrake' # exception/error tracking service
gem 'haml'
gem 'validates_existence', '>= 0.4'
gem 'useragent'
gem 'heroku'

group :development do
    gem 'zeus' # speeds up loading of console and server
    gem 'better_errors' # nicely-formatted UI of errors
    gem 'binding_of_caller' # allows real-time debugging on error breakpoints
    gem 'therubyracer', :platforms => :ruby, :require => 'v8'
end

group :production do

end

# Gems used only for assets and not required
# in production environments by default.
group :assets do
end

gem 'sass-rails',   '~> 3.2.5'
gem 'coffee-rails', '~> 3.2.2'
gem 'uglifier'
gem 'jquery-rails'
gem 'prototype-rails'
gem 'coffee-filter'

The zeus gem requires Linux or Mac OS X See https://github.com/burke/zeus

Remove the zeus gem from your Gemfile, run bundle install , and then retry rails server
