chef - error in installing knife-ec2 plugin -


while installing knife-ec2 plugin.i facing following issue:

root@ip-10-ggg-ff-abc:/opt/chef/embedded/bin# gem install knife-ec2
error: error installing knife-ec2:
mime-types requires ruby version >= 1.9.2.

i think error clear...

one of gems knife-ec2 requires ruby version (1.9.2 or higher). running version of ruby less 1.9.2. upgrade ruby in omnibus package or use ruby version manager install newer ruby.
