[chef] Re: Re: What is the difference between the following following 2 gem installation methods?

Thanks Guys! for clarifying.

Is there any way to make the gem installation conditional? Like `only_if` ? So that the chef-client doesn't install those gems in each run?

    gem_package "mysql" do

      action :install

This is used to install a gem to your system, such as when you're

installing a Ruby application to run as a service.

    r = gem_package "right_aws" do

      version node['aws']['right_aws_version']

      action :nothing

    end

    r.run_action(:install)

    require 'rubygems'

    Gem.clear_paths

This is used to install a gem immediately so you can use the gem in a

Chef recipe. In Chef 0.10.10+ this will be replaced by:

chef_gem "right_aws" do

version node['aws']['right_aws_version']

end
