问题
I am getting this error message:
"It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby."
I have tried entering this command: rvm pkg install libyaml
and I am getting this error message:
"Fetching yaml-0.1.4.tar.gz to /Users/luke/.rvm/archives
Extracting yaml-0.1.4.tar.gz to /Users/luke/.rvm/src

Does anyone know what I am doing wrong? Thanks!

Try this...
Open a new terminal window and:
cd .rvm/src
sudo rm -rf yaml*
(supply your credentials)
cd ~
rvm pkg install libyaml

The current release [was] LibYAML: 0.1.4 (2011-05-30) [in 2012 when I answered this question].
Download the source package: http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz.
To build and install LibYAML, run
$tar zxf yaml-0.1.4.tar.gz
$cd yaml-0.1.4
$ ./configure
$ make
$ make install
OR just:
$brew install libyaml
Next,
$brew install ruby
Good luck.

This worked for me:
- rvm remove 1.9.3
- download http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz
- cp Downloads/yaml-0.1.4.tar.gz .rvm/archives/
- rvm install 1.9.3

Installing ruby with rvm for mac osx, use autolibs to install libyaml and first uninstalling libyaml helps.
This worked for me:
brew uninstall libyaml
rvm autolibs enable
rvm reinstall ruby-2.1.1
