Gem Debugger não será instalado com instalação de pacote

Eu instalei Ruby on Rails usando rvm. Estou usando 2.2.0 Ruby e 4.2.0 Rails. Tentei executar bundle install em um projeto mais antigo que desenvolvi em um PC antigo, mas obtive:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /home/florin/.rvm/gems/ruby-2.2.3/gems/debugger-1.6.8 for inspection.

An error occurred while installing debugger (1.6.8), and Bundler cannot

Make sure that `gem install debugger -v '1.6.8'` succeeds before bundling.

Lendo na internet tentei instalar todas as coisas de desenvolvimento como: sudo apt-get install libpq-dev

sudo apt-get install libmysqlclient-dev
sudo apt-get install libpq-dev
sudo apt-get install libsqlite3-dev
sudo apt-get install libev-dev

mas não funcionou.

A mesma coisa aconteceu comigo quando mudei de Ruby-1.9.3-p385 para Ruby-2.2.3.

Parece que quando você gera o projeto, Rails usará as gems apropriadas para a versão Ruby, que não têm garantia de funcionar para outras versões Ruby.

Nesse caso, o depurador não suporta Ruby após 2.1.1, e você pode fazer isso funcionar substituindo:

gem 'debugger'

com:

gem 'byebug'

em seu Gemfile.
