[chef] Re: Re: Re: Re: How to add ruby lib as depend at LWRP

[Juan Jesús Ojeda Croissier < >]

Hi :-)

Acctually, I did try that before the last solution I put before, but I
got this message:
FATAL: NameError: undefined local variable or method `node' for
#<Class:0xb6c506b4>

So I used @node instead of node:
run_context = Chef::RunContext.new(@node, {})
f = Chef::Resource::AptPackage.new("libsqlite3-ruby", run_context)
f.run_action(:install)

And I got this:
FATAL: NoMethodError: undefined method `cookbook_collection=' for nil:NilClass

I'll keep looking on this.

Thanks for the feedback.
