Quando vi essa gem, achei bem interessante... Se todo mundo usasse teríamos mensagens mais claras que qual lib que está faltando para rodar a gem... Exemplo? O **poltergeist** (que é a gem para executar ) obviamente depende do **phantom.js**. Mas quando você instala ele e não tem phantom instalado, ocorre uma mensagem bem pouco diagnosticável. Com essa gem os nossos problemas acabaram! O projeto é este: [https://github.com/yaauie/cliver](https://github.com/yaauie/cliver). Segundo a própria documentação, é bem fácil usar: ``` # no version requirements Cliver.detect('subl') # => '/Users/yaauie/.bin/subl' # one version requirement Cliver.detect('bzip2', '~> 1.0.6') # => '/usr/bin/bzip2' # many version requirements Cliver.detect('racc', '>= 1.0', '< 1.4.9') # => '/Users/yaauie/.rbenv/versions/1.9.3-p194/bin/racc' # dependency not met Cliver.detect('racc', '~> 10.4.9') # => nil # detect! raises Cliver::Dependency::NotMet exceptions when the dependency # cannot be met. Cliver.detect!('ruby', '1.8.5') # Cliver::Dependency::VersionMismatch # Could not find an executable ruby that matched the # requirements '1.8.5'. Found versions were {'/usr/bin/ruby'=> '1.8.7'} Cliver.detect!('asdfasdf') # Cliver::Dependency::NotFound # Could not find an executable asdfasdf on your path ``` Espero que seja útil.
