come si può vedere è molto lunga hihi:
2)La active non mi funziona nonostante l’installazione con gem install
active support sia andata a buon fine (so’ che c’è la gem anche perchè
facendo gem list mi esce activesupport), ecco l’errore:
irb(main):001:0> require ‘RubyGems’
=> true
irb(main):002:0> gem ‘activesupport’
=> true
irb(main):003:0> require ‘activesupport’

- Ora invece riguardo la sdl, faccio cd e vado nella cartella Lib dove
si trova il file sdl.rb, poi scrivo ‘ruby sdl.rb init’ e poi ‘ruby
sdl.rb install’ mi da errore (questo con altri file di ruby, non posso
nemmeno visualizzare gli esempi delle librerie che mi da errore).

Bhe questo è tutto, se può far comodo la versione di ruby è questa
precisamente:
ruby 1.9.2p180 (2011-02-18) [i386-mingw32]
