Installing libyaml for ruby on a mac osX (Lion)

Question

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
Error running 'tar xmzf /Users/luke/.rvm/archives/yaml-0.1.4.tar.gz -C
/Users/luke/.rvm/src ', 
   please read /Users/luke/.rvm/log/yaml/extract.log

Error running 'make ', please read /Users/luke/.rvm/log/yaml/make.log

Does anyone know what I am doing wrong? Thanks!

Did you read the extract.log and configure.log like the error message instructs? Perhaps post the contents to a gist (gist.github.com). — Casper, May 01 '12 at 01:39

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.

I am getting this after the "./configure" step: make all-recursive Making all in include make[2]: Nothing to be done for `all'. Making all in src make[2]: Nothing to be done for `all'. Making all in . Making all in tests make[2]: Nothing to be done for `all'. Making all in win32 make[2]: Nothing to be done for `all'. luke$ Also, I am not sure if it matters but $brew install ruby does not seem to work for me. I am using rvm to reinstall it. I really appreciate your help! Thanks! – Luke Bessey May 08 '12 at 23:42

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

Try this...

Open a new terminal window and:

(supply your credentials)

cd ~
rvm pkg install libyaml

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
