I'm trying to install CHEF for the first time.
I'm using a MAC as my development machine, deploying to Ubuntu.
chef generate repo WWW // seems to work ok
knife zero bootstrap x.x.x.x --ssh-user root --node-name WWW
WARN: Deprecation CHEF-18 ...
Starting local-mode server in deprecated socket mode
It wants rbnacl, rbnacl-libsodium, crypt-pbkdf
How do I fix this problem? How/where do I install these gems?
