ruby on rails 3 - Heroku: Could not find libv8-3.15.11.1 in any of the sources -

i know there lot of these questions on github (i've looked through of them), none of answers have worked me.

i getting error "could not find libv8-3.15.11.1 in of sources" when seek "git force heroku master." specify version of libv8 in gemfile (with gem "libv8", "~> 3.11.8.13"), , think reflected in gemfile.lock ("libv8 (3.11.8.13)"). don't understand why it's looking version 3.15.11.1 when i've specified 3.11.8.13.

i made sure changes gemfiles committed (when "git status", "nothing commit (working directory clean)."

i tried removing heroku , re-adding (with "git remote rm heroku" , "git force heroku master").

according page:

https://devcenter.heroku.com/articles/rails3x-asset-pipeline-cedar

"therubyracer if using therubyracer or therubyracer-heroku, these gems no longer required , discouraged these gems utilize big amount of memory."

consequently removed these test application. installed node.js on ubuntu local machine , runs fine on heroku.

see question too: rails 3.1 error - not find javascript runtime?
