This is the error after I run bundle install in rails. I'm using rails 4. I already followed the instruction that given but nothings happen.
Gem::RemoteFetcher::UnknownHostError: no such name (https://rubygems.org/gems/has_scope-0.6.0.rc.gem)
An error occurred while installing has_scope (0.6.0.rc), and
Bundler cannot continue.
Make sure that `gem install has_scope -v '0.6.0.rc'` succeeds
before bundling.
then, this is the gemfile
gem 'activeadmin', github: 'gregbell/active_admin'
gem "meta_search"
gem 'bourbon', '3.2.1'
gem 'has_scope', '0.6.0.rc'
Thank you!
