RVM Error Installing ruby-2.2.0

On my mac running OS X 10.9, I was trying to install ruby-2.2.0 using rvm and I repeatedly received an error when it was trying to install with the commands rvm install ruby-2.2.0 and rvm reinstall ruby-2.2.0 after it errored out initially.

The error was:

ruby-2.2.0 - #installing.............

To try to figure out my issue I issued the above commands with –debug and I didn’t receive any valuable feedback from that.

Trying to find information searching for the error I came across the rvm gem list command and when I ran that I received a different error which I wasn’t expecting at all.

rvm gem list error:
    dev-mac:projects bengdovicak$ gem list
    /Users/bengdovicak/.rvm/rubies/ruby-2.1.2/lib/ruby/2.1.0/yaml.rb:4:in `<top (required)>':
    It seems your ruby installation is missing psych (for YAML output).
    To eliminate this warning, please install libyaml and reinstall your ruby.

That gave me helpful feedback on how to fix that error at least that I needed to get libyaml functioning correctly. I am not sure what happened to it.

I then ran:

dev-mac:projects bengdovicak$ brew install libyaml
Warning: libyaml-0.1.6 already installed
dev-mac:projects bengdovicak$ brew reinstall libyaml
==> Reinstalling libyaml
Error: libyaml-0.1.6 already installed
To install this version, first `brew unlink libyaml'
dev-mac:projects bengdovicak$ brew unlink libyaml
Unlinking /usr/local/Cellar/libyaml/0.1.6... 1 symlinks removed
dev-mac:projects bengdovicak$ brew reinstall libyaml  

rvm gem list then worked fine and listed my gems. I decided to try installing ruby-2.2.0 again and it installed just fine. Reinstalling libyaml fixed my problems.
