Forum: JRuby NameError: uninitialized constant Psych::Yecht with jruby 1.7.1

The Problem
-----------

When I use jruby 1.7.1 in my rails app and run

'bundle exec rspec'

I get

'NameError: uninitialized constant Psych::Yecht'


What I want
----------

To run rspec under jruby 1.7.1.


What I've Tried
------------

* Adding gem "psych", "~> 1.3.4" to my gem file
* Installing libyaml using homebrew - 'brew install libyaml'


More Details
----------

* rvm list gives:

   jruby-1.6.8 [ x86_64 ]
=> jruby-1.7.1 [ x86_64 ]
 * ruby-1.9.3-p327 [ x86_64 ]

Hi John,

As you now know, because we sit next to each other, and for the benefit 
of others on this list, the problem was caused by an issue in the 
configatron gem that is not compatible with JRuby 1.7

See https://github.com/wistia/wistia-api/pull/3 for more details

Many Thanks

Adrian
