ruby on rails执行RAILS_ENV=production rake assets:precompile报warning

ruby on rails执行RAILS_ENV=production rake assets:precompile报warning如下：

[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.

解决方案：

application.rb中加入config.i18n.enforce_available_locales = true
