Witam. Po aktualizacji Railsów nie mogę uruchomić serwera:
$ rails server
/usr/lib/ruby/1.9.1/rubygems.rb:238:in `activate': can't activate activesupport (= 3.0.3, runtime) for ["railties-3.0.3"], already activated activesupport-2.3.5 for ["rails-2.3.5"] (Gem::LoadError)
from /usr/lib/ruby/1.9.1/rubygems.rb:254:in `block in activate'
from /usr/lib/ruby/1.9.1/rubygems.rb:253:in `each'
from /usr/lib/ruby/1.9.1/rubygems.rb:253:in `activate'
from /usr/lib/ruby/1.9.1/rubygems.rb:1119:in `try_activate'
from <internal:lib/rubygems/custom_require>:32:in `rescue in require'
from <internal:lib/rubygems/custom_require>:29:in `require'
from script/rails:6:in `<main>'
Co mogę z tym zrobić?
