Error Heroku with rdiscount gem

Question

나는 내가 그것을 필요로 할지도 모른다고 생각한 것을 위해 rdiscount gem을 사용했다. 그러나 나는 그것을 unistalled했다. 내가 Heroku가에 응용 프로그램을 배포하려고 할 때 나는 다음과 같은 얻을 :

나는 보석 gem unistall rdiscount하지만 아무것도를 제거해야합니다. 그런 다음 heroku 오류 당 다시 설치하려고했지만 여전히 아무것도하지 못했습니다.

Gemfile : RDiscount이 문제를 알고있다 루비 1.9.2을 사용하는

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

end 

Answer 1

Heroku가 기본 설정됩니다.

나중에 루비 1.9.3 또는를 사용하도록 Gemfile을 수정하십시오 :

source :rubygems 
ruby "1.9.3" 

gem 'rdiscount'
