Bundle install is throwing error when installing coffee-script-source -v
'1.6.3'

I'm using Ruby 2.0.0 and Rails 4 but I'm getting an error with
coffee-script when I generate new rails project
Installing coffee-script-source (1.6.3) Errno::EACCES: Permission denied -
/usr/local/rvm/gems/ruby-2.0.0-p247/build_info/coffee-script-source-1.6.3.info
An error occurred while installing coffee-script-source (1.6.3), and
Bundler cannot continue. Make sure that gem install coffee-script-source
-v '1.6.3' succeeds before bundling.
