My application has had the following lines without any trouble in recent versions of rails:

gem 'linguistics' # in Gemfile

Linguistics::use(:en, :installProxy => :en) # In environment.rb

Recently I upgraded from Ruby 1.8.7 to Ruby 1.9.2 and am using the edge version of Rails. When I start the server I now see the following:

=> Booting WEBrick
=> Rails 3.1.0.beta1 application starting in development on

=> Ctrl-C to shutdown server Exiting /Users/alextan/.rvm/gems/ruby-1.9.2-p180/gems/linguistics-1.0.8/lib/linguistics.rb:177:in

Any idea on how I can fix this? Is this an incompatibility between Linguistics and Ruby 1.9.2?

    I think its mainly a rails compatibility problem, because in the commits 1.9.2 compat is mentioned, try on after another, not both together, to ensure, 1.9.2 and rails 3 works, after that switch to edge rails.

    You may want to try, if there is a actual version out there, try (include this version then in your gemfile):

    gem update linguistics --pre

    OR be sure to have it updated in your gemfile

    gem 'linguistics', :git => 'https://github.com/ged/linguistics.git'
