Ruby debug ide с ошибкой ubuntu

У меня слишком много ошибок, когда я хочу установить ruby-debug и ruby-debug-ide.

Такая ошибка (установка пакета):

An error occurred while installing ruby-debug-base19 (0.11.24), and Bundler cannot continue.
Make sure that `gem install ruby-debug-base19 -v '0.11.24'` succeeds before bundling.

В том же решении:

gem install ruby-debug-base or ruby-debug-base19

та же ошибка,

ERROR: Failed to build gem native extension.

Кто-нибудь знает, что делать?
