Erreur Heroku avec gem rdiscount

Question

J'ai utilisé la gemme rdiscount pour quelque chose que je pensais que je pourrais avoir besoin mais je l'ai désistée. Quand j'ai essayé de déployer l'application sur Heroku-je obtenir les éléments suivants:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

je désinstaller le bijou gem unistall rdiscount mais rien. J'ai ensuite essayé de le réinstaller par erreur heroku mais toujours rien.

Gemfile:

source 'http://rubygems.org' 

gem 'rails', '3.2.11' 
gem 'bootstrap-sass', '2.3.0' 


group :development, :test do 
    gem 'sqlite3', '1.3.5' 
    gem 'rspec-rails', '2.11.0' 
    gem 'guard-rspec', "1.2.1" 
    gem 'guard-spork', '1.4.2' 
    gem 'spork', "0.9.2" 
    gem 'guard-livereload' 
end 

group :assets do 
    gem 'sass-rails', '3.2.5' 
    gem 'coffee-rails', '3.2.2' 
    gem 'uglifier', '1.2.3' 
end 

gem 'jquery-rails', '2.0.2' 

group :test do 
    gem 'capybara', '1.1.2' 
    gem 'rb-fsevent', "0.9.1", :require => false 
    gem 'factory_girl_rails', "4.1.0" 
end 

group :production do 
    gem 'pg', '0.12.2' 
end 

Answer 1

par défaut Heroku à l'aide de Ruby 1.9.2 qui RDiscount a connu des problèmes avec.

S'il vous plaît modifier votre Gemfile utiliser Ruby 1.9.3 ou version ultérieure:

source :rubygems 
ruby "1.9.3" 

gem 'rdiscount'
