我spec/使用rspec-puppet-init. 但是，我收到了这个奇怪的错误：Undefined method find_by_name for Gem::Specification:Class。我正在ruby 1.8.7为 RHEL6 运行。

$ rake spec
(in /etc/puppet/modules/profiles)
rake aborted!
undefined method `find_by_name' for Gem::Specification:Class
/etc/puppet/modules/profiles/Rakefile:22
(See full trace by running task with --trace)

然后我运行它--trace并得到这个：

rake aborted!
undefined method `find_by_name' for Gem::Specification:Class
/etc/puppet/modules/profiles/Rakefile:22
/usr/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2382:in `load'

/usr/lib/ruby/gems/1.8/gems/rake-0.8.7/bin/rake:31
/usr/bin/rake:19:in `load'
/usr/bin/rake:19

在我的 Rakefile 中（这是自动生成的）：

require 'rake'
require 'rspec/core/rake_task'

desc "Run all RSpec code examples"
RSpec::Core::RakeTask.new(:rspec) do |t|
  t.rspec_opts = File.read("spec/spec.opts").chomp || ""
end

SPEC_SUITES = (Dir.entries('spec') - ['.', '..','fixtures']).select {|e| File.directory? "spec/#{e}" }
namespace :rspec do
  SPEC_SUITES.each do |suite|
    desc "Run #{suite} RSpec code examples"
    RSpec::Core::RakeTask.new(suite) do |t|
      t.pattern = "spec/#{suite}/**/*_spec.rb"
      t.rspec_opts = File.read("spec/spec.opts").chomp || ""
    end
  end
end
task :default => :rspec

begin
  if Gem::Specification::find_by_name('puppet-lint')
    require 'puppet-lint/tasks/puppet-lint'
    PuppetLint.configuration.ignore_paths = ["spec/**/*.pp", "vendor/**/*.pp"]
    task :default => [:rspec, :lint]
  end
rescue Gem::LoadError
end

知道有什么问题吗？无论如何，我都不是红宝石专家。

根据@engineersmnky，我运行了以下命令：

$ gem update --system

然后我不得不重新运行这些命令：

$ sudo gem install rake
$ sudo gem install puppetlabs_spec_helper
$ sudo gem install puppet-lint
