Vagrant delete Chef node and Client on destroy

Vagrantfile

module Vagrant
   module Provisioners
    class ChefClient
      def cleanup
        env[:ui].info "Attempting to remove client #{env[:vm].config.vm.host_name}"
        `knife client show #{env[:vm].config.vm.host_name}`
        if $?.to_i == 0
          env[:ui].info "Removing client #{env[:vm].config.vm.host_name}"
          `knife client delete #{env[:vm].config.vm.host_name} -y`
        end
        env[:ui].info "Attempting to remove node #{env[:vm].config.vm.host_name}"
        `knife node show #{env[:vm].config.vm.host_name}`
        if $?.to_i == 0
          env[:ui].info "Removing node #{env[:vm].config.vm.host_name}"
          `knife node delete #{env[:vm].config.vm.host_name} -y`
        end
      end
    end
  end
end

I get the following:

$ vagrant destroy

/Users/sergio/.rvm/rubies/ruby-1.9.3-p327/lib/ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find chef (>= 0) amongst [archive-tar-minitar-0.5.2, childprocess-0.3.5, erubis-2.7.0, ffi-1.1.5, i18n-0.6.1, json-1.5.4, log4r-1.1.10, net-scp-1.0.4, net-ssh-2.2.2, vagrant-1.0.5] (Gem::LoadError)

Which is just a listing of gems from

/Applications/Vagrant/embedded/gems/gems/

Any idea on how to fix it?

What if Vagrant is configured to take node name from somewhere? Mine is configured like this:

NODE_FILE = "./chef.node"

I think in this case this snippet will not work. Also it gives an error:

rubygems_integration.rb:252:in block in replace_gem': chef is not part of the bundle. Add it to Gemfile.`

@FractalizeR I was having similar issue, I read most of conversations and no luck with any workaround provided. You may got here as well (hashicorp/vagrant#2476)

Then I tried similar thing, I removed/uninstall vagrant and install it again. However, I got another error, which sounds better:

stderr: WARNING: No knife configuration file found ERROR: Your private key could not be loaded from /etc/chef/client.pem

It might help.
