[chef] Re: Calling chefdk chef command from a bundle

I think you might be missing the environment stuff that you get from chef shell-init

Hi,

I'm writing a couple of thor jobs to configure a workstation for Chef development. One of the things I want to do is to install a few gems into the chefdk installed on the system if they don't exist. I thought it would be simple enough to just shell out and run the chef command to install these gems (i.e. `chef gem install kitchen-ec2` but calling the chef command, or indeed the ChefDK ruby from within my bundle results in an error stating that a gem can't be found.

So if I run bin/thor myorg:check (where bin/thor is a binstub in my bundle) and in the thor jobs there's any command that calls the chef executable, e.g.

`chef -v`  then I get the following:

/Library/Ruby/Gems/2.0.0/gems/bundler-1.10.3/lib/bundler/spec_set.rb:92:in `block in materialize': Could not find rake-10.4.2 in any of the sources (Bundler::GemNotFound)

    from /opt/chefdk/embedded/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:54:in `require'

or system('chef -v') then I get the following error:
Could not find rake-10.4.2 in any of the sources
Run `bundle install` to install missing gems.

My bundle has that rake gem but for ruby v2.0.x instead of v2.1.x which the chefdk uses. I'm guessing that running from within a bundle is messing up the bundle environment that the chef executable uses, but I've not the knowlege of how this works to get it working.

Is there any way around this (other than use thor from the system ruby, which would be the fallback, but not ideal)? Will dropping certain environment variables related to bundler when shelling out fix the problem?
