Vagrant

Вагрант это такая ~~неведомай йобаная хуйня~~ надстройка над паппетом или чифом и виртуалбоксом

Установка

Invalid gemspec in [/var/lib/gems/1.8/specifications/json-1.5.4.gemspec]: invalid date format in specification: "2011-08-31 00:00:00.000000000Z"

Solution is edit broken "gemspec" files ( [/var/lib/gems/1.8/specifications/json-1.5.4.gemspec ). Change "s.date" into :

s.date = %q{2011-08-31}
