undefined local variable or method for extended module

NOTE: the question was edited to reflect the issue.

i would like to work with knife-api rubygem. enclosed a snippet of my code

require 'chef'
require 'chef/knife'
require 'knife/api'

module X
  module Y
    module Z
      include Chef::Knife::API

      def self.foo
        resp = knife_capture :search, ['*:*']
        puts resp
      end
    end
  end
end

when X::Y::Z.foo is called, it returns

gems/knife-api-0.1.7/lib/knife/api.rb:41:in `ensure in knife_capture': undefined local variable or method `revert_io_channels' for X::Y::Z (NameError)

it appears that he enclosing scope functions (Chef::Knife within knife-api) are inaccessible within X::Y::Z.foo.

how should i make this work?

Solution

  • In a complete non-answer, do not use the knife-api gem. It should not exist. The correct gem to use if you want to access Chef API data from Ruby code is chef-api (I know, we're real creative with names). If you want to do something very small, check out the knife exec command which just exposes the raw Chef object API (not as refined as chef-api, but built in).
