Rake fails on creation of a new Ruby on Rails application -


on command line, when go create new ruby on rails application, fails on:

run bundle install

it says: 

fetching gem metadata https://rubygems.org/.......... fetching gem metadata https://rubygems.org/.. resolving dependencies...  argumenterror: invalid byte sequence in utf-8 error occurred while installing rake (10.1.0), , bundler cannot continue. make sure `gem install rake -v '10.1.0'` succeeds before bundling.

after doing asks (which doesn't produce error), says gem installed. i've tried reinstalling bundler , says 1 gem installed.
