I am getting the following when attempting to run rspec:

Any thoughts on what could be causing this?

I'm not sure. Can you give me some code to reproduce this?

Tenderlove I could use your extensive wisdom on this one! I'm hitting this same exception as above when running anything after adding gem 'psych' to my gemfile (and running bundle install). We're using Rails 3.2.8. I'm guessing this is some kind of incompatibility but not sure how to resolve. I tried various versions of Psych (2.0.4-2.0.8). This is the only thing I found online with my exact error...

The whole reason why I wanted to explicitly include the psych gem is because we are internally using very old versions and wanted to ensure good JSON parse support: DEBUG: Psych version: 1.2.2 DEBUG: Psych libyaml version: 0.1.4

Here's the stacktrace:
