what should solve problem?

i had similar issue , after reinstalling rvm (a headache) couple days later came back. time tried using comments isolate gems in gemfile causing problem. noticed new gems. tried 

gem install <problem_gem>  error:  not find valid gem 'problem_gem' (>= 0), here why:       unable download data https://rubygems.org/ - no such name      (https://rubygems.org/latest_specs.4.8.gz)

this made me think wasn't connected internet. once connected again.

bundle worked!

bundle install
