When using this command in the middle of my RailsTutorial ( on my laptop setup) :
rvm use 2.0.0@railstutorial_rails_4_0 --create --default
I receive the following errors:
laptop:rubygems-1.8.25 USER_NAME$ rvm use 2.0.0@railstutorial_rails_4_0 --create --default

It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.

I've reinstalled libyaml, and reinstalled ruby, and it all returns back to these errors. No matter what I do, I always end up back at this list of errors.
