Could not find "/Users/tvd/.rvm/gems/ruby-1.9.3-p0@alchemy/bundler/gems/fancygrid-475f31b7d98c/lib/generators/../../config/initializers/fancygrid.rb" in any of your source paths.
Please invoke Fancygrid::Generators::InstallGenerator.source_root(PATH) with the PATH containing your templates. Currently you have no source paths.
The generators dont work with rails 3.1 since fancygrid was build for rails 3.0. For now you have to do all the stuff the generators do manually. I try to fix that this weekend.
