如何正确设置 puppet-rspec?

How to setup puppet-rspec correctly?

我正在按照 here

的说明进行操作
gem install rvm
gem install bundle

# Demo dir

# Gemfile
source "https://rubygems.org"

gem 'rspec-puppet', :require => false
gem 'puppetlabs_spec_helper',  :require => false
gem 'puppet', '~> 3.7.5'
gem 'rspec-puppet-facts'

# spec_helper.rb
require 'puppetlabs_spec_helper/module_spec_helper'
require 'rspec-puppet-facts'
include RspecPuppetFacts     

现在当我 运行 bundle exec rake spec 我得到以下错误:

/usr/bin/ruby -I/usr/lib64/ruby/gems/1.8/gems/rspec-core-3.3.1/lib:/usr/lib/ruby/gems/1.8/gems/rspec-support-3.3.0/lib /usr/lib64/ruby/gems/1.8/gems/rspec-core-3.3.1/exe/rspec --pattern spec/\{classes,defines,unit,functions,hosts,integration\}/\*\*/\*_spec.rb --color

关于如何解决这个问题有什么想法吗?或者有人可以提供一些明确的说明,说明如何让它在 CentOS 6.5 机器上运行吗?

Gemfile 更新为以下 运行 bundle update 有效:

source 'https://rubygems.org'

if puppetversion = ENV['PUPPET_GEM_VERSION']
  gem 'puppet', puppetversion, :require => false
else
  gem 'puppet', '3.7.5' 
end


gem 'metadata-json-lint'
gem 'puppetlabs_spec_helper', '>= 0.1.0'
gem 'puppet-lint', '>= 1.0.0'
gem 'facter', '>= 1.7.0'
gem 'rspec-puppet-facts' 


# rspec must be v2 for ruby 1.8.7
if RUBY_VERSION >= '1.8.7' and RUBY_VERSION < '1.9'
  gem 'rspec', '~> 2.0'
end
