Why I am getting Could not find multi_json-1.3.1 in any of the sources?
bundler, deployment, heroku, ruby-on-rails, ruby-on-rails-3
Solution
Delete the Gemfile.lock file, and run bundle install. This works for me!
Problem
I have a simple Rails application I want to deploy to Heroku. When I run the below command ``` git push heroku master ``` The below error message is displayed. ``` Could not find multi_json-1.3.1 in any of the sources ! ! Failed to install gems via Bundler. ! ! Heroku push rejected, failed to compile Ruby/rails app ``` Here is my Gemfile ``` gem 'rails', '3.2.3' gem 'pg' group :assets do gem 'sass-rails', '~> 3.2.3' gem 'coffee-rails', '~> 3.2.1' gem 'therubyracer', :platform => :ruby gem 'uglifier', '>= 1.0.3' end gem 'jquery-rails' ```
