ruby unexplained syntax error ** unexpected tPOW

问题

running this :

 knife cookbook upload compat_resource

failing due to syntax error:

FATAL: /apps/chef-repo/cookbooks/compat_resource/files/lib/chef_compat/copied_from_chef/chef/property.rb:56: syntax error, unexpected tPOW, expecting ')'
FATAL:      new(**options)
FATAL:            ^

I'm suspecting that the version that's running the knife is under 2.

how can I run knife with a specific ruby verion.

how can I reinstall chef with ruby > 2 ?

Do not install Chef using rubygems, but use ChefDK on your workstation instead. This ships with a complete ruby stack (call this good or bad..) and thus ensures that the Chef gems and the ruby version are compatible.
