    from /Users/macbook/.rvm/rubies/ruby-2.1.0/lib/ruby/2.1.0/psych.rb:369:in `parse_stream'

I have searched hours trying to figure this out so any help would be greatly appreciated. I take it this is a simple fix, so apologize in advance for this easy question.

It could be that you are using newer version of ruby i.e 2.1.0 which was just released today and the relevant gems for rails are not fully compatible with it.

You can install rails in ruby 2.0.0 through RMV i.e

$ rvm install 2.0.0
$ rvm use 2.0.0
$ ruby -v 
# should retrun 2.0.0-p...
$ gem install rails
