Pass an empty run_context into the ChefGem.new call, created like this?

run_context = Chef::RunContext.new(Chef::Node.new, {}, Chef::EventDispatch::Dispatcher.new)

Subject: [chef] Using resources in a library?

Hi everyone,

I'm trying to add a gem dependency to a library. I found a couple conversations talking about using resources in libraries in my travels:

• http://stackoverflow.com/questions/21908433/using-class-methods-from-libraries-in-a-recipe
• http://lists.opscode.com/sympa/arc/chef/2011-12/msg00171.html
  

In both, the most reasonable advice is to create an instance of the resource's class and call #run_action(:whatever) to get it to execute immediately. From my testing, this doesn't work, with the problem specifically being this code snippet and error: https://gist.github.com/notnmeyer/04bc1c0be0e41504cd62

My first thought was to pass it run_context... But there's no run_context at this point for me to pass to the resource's constructor.

To demonstrate in further detail, I put together a quick cookbook with a Test Kitchen suite: https://github.com/notnmeyer/gem-dep

Any thoughts? What's the proper way to immediately execute a resource during compile time?

Thanks!

Nate
