Unable to resolve Ruby error (missing psych)

Question

Whenever I run something with Ruby on my server, I get the following error:

/usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/yaml.rb:56:in `

        

Answer 1

In case people still hit this, I fixed it using the new autolibs feature in RVM, which automatically installs dependencies using your homebrew libraries (check out rvm help autolibs for info.)

rvm reinstall 1.9.3 --autolibs=2
