Не удается установить Mysql gem на сервере Ubuntu

Question

Я добавил mysql gem в свой файл gem, но когда я запустил bundle install, он показывает мне ошибку ниже.

An error occurred while installing mysql (2.9.1), and Bundler cannot continue. Make sure that `gem install mysql -v '2.9.1'` succeeds before bundling. 

Я устанавливаю этот драгоценный камень на моей Ubuntu machine.I я использую Рельсы версии 4.2.0 и рубин 2.1.7.I я объяснял мю Gemfile ниже.
