Please install libyaml and reinstall your ruby

Question

libyaml warning doesn\'t go away, even if you install libyaml

gem install bundler
/home/ec2-user/.rvm/rubies/ruby-1.9.3-p392/lib/ruby/1.9.1/yaml.rb:56:in `&l         


        

Answer 1

If using homebrew, a temporary fix that worked for me was to run:

brew unlink libyaml && brew link libyaml

plus you may also need to run:

brew unlink openssl && brew link --force openssl

See this issue thread for more details: https://github.com/wayneeseguin/rvm/issues/2689

Answer 2

First remove any previous docs of yaml by

cd .rvm/src
sudo rm -rf yaml*

Then you can do rest of the install by -

rvm pkg install libyaml

P.S You will need to reinstall ruby after this.

UPDATE: If rvm pkg seems to be deprecated. You can compile a source on your own. All you gotta do is download the latest version of libyaml from http://pyyaml.org/download/libyaml/

tar zxf yaml-0.1.4.tar.gz
cd yaml-0.1.4
./configure
make
make install

---

UPDATE2: BTW, you could still use rvm pkg and/or when reinstalling ruby make sure to enbale autolibs by \curl -L https://get.rvm.io | bash -s stable --rails --autolibs=enable

Answer 3

A friend of mine had a similar problem on his mac.

brew install libyaml

ended up working for us and we were able to avoid a reinstall of ruby.
