On pushing the Rails4 code to heroku I get the following error, this has started happening in last 2 days, which otherwise a smooth process
Writing config/database.yml to read from DATABASE_URL
-----> Preparing app for Rails asset pipeline
Running: rake assets:precompile

Here is entry from my production.rb
config.assets.initialize_on_precompile = true
I am able to run RAILS_ENV=production rake assets:precompile locally. Though I am not pushing the precompiled assets to the server.
I am get I18n-js 2.1.2 version installed through my gem files, its Rails4 server running for me.
I got rid of i18n-js rails gem, to get the problem fixed. I was using it minimally so replaced it with some small code of mine.
There are problems with the Gem and Rails 4 when deploying on Heroku.
