I am running Mac OSX 10.9.1 and I am using RVM to manage Ruby v2.0.0-p353.
When I try to install Rails I get this error:
Ryans-MacBook-Air-2:~ ryan$
Following Steps worked for me -
Go to corrupted package/gem location
$ cd /Users/ryan/.rvm/gems/ruby-2.0.0-p353/cache/
Remove corrupted package/gem
$ rm i18n-0.6.9.gem
Now install that specific gem OR $ bundle install
$ bundle install
