O Gem Debugger não instala com a instalação por pacote

Question

Eu instalei o ruby on rails usando rvm. Eu estou usando 2.2.0 ruby e 4.2.0 Rails. Eu tentei executar o pacote de instalação em um projeto mais antigo que eu desenvolvi em um antigo PC, mas eu recebo:

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

    /home/florin/.rvm/rubies/ruby-2.2.3/bin/ruby -r ./siteconf20151003-6297-foug8b.rb extconf.rb

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

extconf failed, exit code 1

Gem files will remain installed in /home/florin/.rvm/gems/ruby-2.2.3/gems/debugger-1.6.8 for inspection.
Results logged to /home/florin/.rvm/gems/ruby-2.2.3/extensions/x86_64-linux/2.2.0/debugger-1.6.8/gem_make.out
An error occurred while installing debugger (1.6.8), and Bundler cannot
continue.
Make sure that 'gem install debugger -v '1.6.8'' succeeds before bundling.

Lendo a internet Eu tentei instalar todas as coisas de desenvolvimento como: sudo apt-get instala o 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.

Eu tive a mesma coisa quando me mudei do ruby-1.9.3-p385 para o ruby-2.2.3.

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

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

gem 'debugger'

com:

gem 'byebug'

no seu Gemfile.
