ruby - InstallError installing ember-cli-rails -


i'm new ruby i'm sure there's i've overlooked, don't know what.

i'm trying install rails app in bundle.

$ bundle install --path vendor/bundle

many gems work, 

installing ember-cli-rails 0.7.0 gem::installerror: ember-cli-rails requires ruby version >= 2.1.0.

i think i'm running acceptable version of ruby...

$ bundle exec ruby --version ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-darwin14]    $ ruby --version ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-darwin14]

any ideas of what's wrong?
