Deploying to EC2 using Rubber on Windows

I'm trying to deploy my Rails app to an Amazon EC2 instance but keeping getting the same error.

Trying to enable root login

c:/RailsInstaller/Ruby2.0.0/lib/ruby/gems/2.0.0/gems/rubber-2.8.0/lib/rubber/recipes/rubber/setup.rb:173:in `read': No such file or directory - /etc/hosts (Errno::ENOENT)

This error points to this block in that file

desc <<-DESC
  Sets up local aliases for instance hostnames based on contents of instance.yml.
  Generates/etc/hosts for local machine
DESC
required_task :setup_local_aliases do
  hosts_file = '/etc/hosts'

  # Generate /etc/hosts contents for the local machine from instance config
  delim = "## rubber config #{rubber_env.domain} #{Rubber.env}"
  local_hosts = delim + "\n"
  rubber_instances.each do |ic|
    # don't add unqualified hostname in local hosts file since user may be
    # managing multiple domains with same aliases
    hosts_data = [ic.full_name, ic.external_host, ic.internal_host]

    # add the ip aliases for web tools hosts so we can map internal tools
    # to their own vhost to make proxying easier (rewriting url paths for
    # proxy is a real pain, e.g. '/graphite/' externally to '/' on the
    # graphite web app)
    if ic.role_names.include?('web_tools')
      Array(rubber_env.web_tools_proxies).each do |name, settings|
        hosts_data << "#{name}-#{ic.full_name}"
      end
    end

    local_hosts << ic.external_ip << ' ' << hosts_data.join(' ') << "\n"
  end
  local_hosts << delim << "\n"

  # Write out the hosts file for this machine, use sudo
  *LINE 173* existing = File.read(hosts_file)
  filtered = existing.gsub(/^#{delim}.*^#{delim}\n?/m, '')

  # only write out if it has changed
  if existing != (filtered + local_hosts)
    logger.info "Writing out aliases into local machines #{hosts_file}, sudo access needed"
    Rubber::Util::sudo_open(hosts_file, 'w') do |f|
      f.write(filtered)
      f.write(local_hosts)
    end
  end
end

I added the text *LINE 173* to the actual line the error is references.

I found this Google Group thread about it, but I'm unsure how to change the path for Windows

Any help would be appreciated. Again, I'm trying to deploy Rails app to EC2 instance on a Windows 8 machine.

The equivalent file in Windows is

C:\Windows\System32\drivers\etc\hosts

This code may have difficulties writing to that file since it requires privileged access.
