[Hector Castro < >]

In a scenario where you use the following approach to make a gem available immediately:

    r = gem_package "right_aws" do

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

      action :nothing

    end

    r.run_action(:install)

Is there an established way to execute `include_recipe` before?  I'm running into a situation where the gem I want available immediately needs packages for compiling native extensions.  I'd like `include_recipe "build-essential"` to execute first.

Right now I'm using something like this to replicate the build-essential cookbook:

    fog_dependencies.each do |fog_dependency|

      d = package fog_dependency do

        action :nothing

      end

      d.run_action(:install)

    end

The provider is idempotent and will not attempt to install the gem if it is installed.

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

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
