Hi @ton31337,

We are actually using toml-rb instead of toml ruby gem. We made this change in #98. Looking at both projects, toml-rb appears to be more active compared to toml. Other than that, I can't say I understand why we moved to toml-rb though. @alvaromorales maybe able to speak to that.

Is there another chef cookbook that has a toml depdendency?

This helped until we have different namespace chef_gem 'toml' { action :remove }

@alaa, ah good workaround, but I would imagine its removing and installing toml gems over and over again during converges.

alright as part of debugging #144, chef 13 now depends on inspec ref: https://github.com/chef/chef/blob/122f2804f573977f9d88d4987988cd68ba785bed/Gemfile#L24 And inspec depends on toml. While the maintainer of toml gem isn't so frequent, I'm going to based on that chef depends toml and that the chef community is far greater than the community of the toml.

WIth that i'm going to go ahead and approve this PR.
