Trying to integrate Community Engine into my application

Question

Error

Bundler could not find compatible versions for gem "multi_json": In Gemfile: community_engine (>= 0) ruby depends on multi_json (~> 1.0.0) ruby uglifier (>= 1.0.3) ruby depends on multi_json (1.3.6) 

Gemfile

 gem 'rails', '3.2.6' gem 'sqlite3' gem 'json' group :assets do gem 'sass-rails', '~> 3.2.3' gem 'coffee-rails', '~> 3.2.1' gem 'uglifier', '>= 1.0.3' end gem 'jquery-rails' gem 'community_engine', :github => 'bborn/communityengine', :branch => 'rails3' 

doubt

always gives the same error despite following all the instructions in the README FILE file for the community engine

Answer 1

add gem "multi_json" to the gemfile

delete the file Gemfile.lock

And then run bundle install

This helped me overcome the above error.
