   The Ruby Racer requires libv8 ~> 3.11.8
   to be present on your system in order to compile
   and link, but it could not be found.
   In order to resolve this, you will either need to manually
   install an appropriate libv8 and make sure that this
   build process can find it. If you install it into the
   standard system path, then it should just be picked up
   automatically. Otherwise, you'll have to pass some extra
   flags to the build process as a hint.
   If you don't want to bother with all that, there is a
   rubygem that will do all this for you. You can add
   following line to your Gemfile:
   gem 'libv8', '~> 3.11.8'
   We hope that helps, and we apologize, but now we have
   to push the eject button on this install.
   thanks,
   The Mgmt.

So it seems that there is now a known problem that has no work around that i know of

Answer 1

I had the same problem and tried one of the suggestions (use the known working therubyracer):

# Gemfile
gem 'therubyracer', '0.10.2', :platforms => :ruby

That's it. I can deploy to Heroku again.
