gemfile contents info!

source 'https://rubygems.org'  gem "thin" gem "rack-contrib"  gem "middleman" gem "middleman-livereload", :git => "https://github.com/middleman/middleman-livereload.git" gem "middleman-smusher", :git  => "https://github.com/middleman/middleman-smusher.git" gem "middleman-favicon-maker", :git => "https://github.com/follmann/middleman-favicon-maker.git"   gem "slim" gem "compass-rgbapng" gem "sassy-buttons"  group :development   gem 'heroku'   gem 'foreman'   gem 'therubyracer-heroku', '0.8.1.pre3'   gem 'oj' end  group :production   gem 'therubyracer-heroku', '0.8.1.pre3'   gem 'oj' end 

so, ideas fix issue?

please use current version of therubyracer (0.11.4 of writing), , not therubyracer-heroku. no longer needed since main gem compatible heroku , no longer maintained.

the ordinary gem compatible heroku just

gem "therubyracer" 

in gemfile should trick
