Example of Rake tasks for dealing with Vagrant

rake_helper.rb

#NOTA: this is actually rake/helper.rb but gists can't named files as directories

require 'vagrant'

class VM
  def initialize(opts=nil)
    opts ||= {ui_class: Vagrant::UI::Colored}
    @env = Vagrant::Environment.new(opts)
    @vm = @env.primary_vm
  end

  def project_path
    @vm.config.vm.shared_folders['v-project'][:guestpath]
  end

  def check_if_alive
    raise "Must run `vagrant up`" if [email protected]?
    raise "Must be running!" if @vm.state != :running
  end

  def cli(command=nil)
    @env.cli(command) if command
  end

  def sudo(command=nil)
    check_if_alive
    @vm.channel.sudo(command) if command
  end

  def execute(command=nil, cwd=nil)
    check_if_alive
    cwd ||= project_path
    command = "cd #{cwd}; #{command}"

    # Some code borrowed from Vagrant::Command::SSH.ssh_execute 
    exit_status = 0
    
    exit_status = @vm.channel.execute(command, :error_check => false) do |type, data|
      channel = type == :stdout ? :out : :error
      case type
      when :stdout
        color = :green
      when :stderr
        color = :red
      else
        color = :clear
      end

      # Print the SSH output as it comes in, but don't prefix it and don't
      # force a new line so that the output is properly preserved
      @vm.ui.info(data.to_s,
                  :prefix   => false,
                  :new_line => false,
                  :channel  => channel,
                  :color    => color)
    end

    # Exit with the exit status we got from executing the command
    exit exit_status
  end
end

Rakefile

load 'rake/helper.rb'

desc "Set up the VM"
task :up do
  vm = VM.new
  vm.cli('up')
end

desc "Shutdown the VM"
task :graceful_down do
  vm = VM.new
  vm.sudo('halt')
end

desc "Start sinatra app"
task :start_sinatra do
  vm = VM.new
  status = vm.execute('rackup -D')
  raise "It didn't start" if status > 0
end

desc "Run tests at the sinatra app"
task :tests do
  vm = VM.new
  vm.execute('rake features')
end

Vagrantfile

  config.vm.box = "base"
  config.vm.box_url = "http://files.vagrantup.com/lucid32.box"

I followed this, and have been getting and odd error I just can't seem to get around. Google is failing me again. I have the latest vagrant (1.3.3) on windows 7 and I can rake, but I get this error

any ideas on corrections to get this going?

how does "require 'vagrant'" work with Vagrant 1.1+? are you guys using the gem install of vagrant?

wich gem vagrant did you install ?
