Как исправить ошибки, выдаваемые при запуске сервера проекта?

Всем доброго времени суток!
Только что перешел на ubuntu и сразу сталкиваюсь с проблемами при запуске сервера проетка Blog на Ruby on Rails.

anton@Anton:~/Blog$ rails server

anton@Anton:~/Blog$ bundle check
The Gemfile's dependencies are satisfied


А после bundle у меня установились какие-то gem'ы, но это не помогло.

Вам ведь сервер по-человечески пишет в чём проблема:
/home/anton/.rvm/gems/ruby-2.3.0/gems/bundler-1.12.5/lib/bundler/runtime.rb:89:in `rescue in block (2 levels) in require': There was an error while trying to load the gem 'uglifier'. (Bundler::GemRequireError)

Выполните в консоли:
sudo apt-get install nodejs
Потом ещё раз запустите bundle
