Você provavelmente vê essas mensagens de erro quando roda Rails 2.3.8 ou mais antigo no mesmo servidor com o novo Rails 3 para cima.
Para arrumar isso existe 2 possíveis soluções:
Solução 1:
- Crie o arquivo: config/preinitializer.rb
- Com o conteúdo abaixo:
require 'rubygems'
begin
gem 'i18n', "~> 0.4.0"
rescue LoadError
# no biggie, optional anyway
end
- Reinicie o servidor web
Solução 2:
No terminal:
gem uninstall i18n
gem install i18n -v 0.4.0
