Ho fatto l’update di alcune gem, tra cui rails da 3.0 a 3.0.1 e  
bundler ed ora mi ritrovo col seguente errore:

bundle install  
/home/user/jruby/lib/ruby/site\_ruby/1.8/rubygems/package/tar\_input.rb:111:in  
`initialize’: No metadata found! (Gem:📦:FormatError)

Ma percheeeeeeeeeeeeeeee???

ciao Mauro,

prova a cancellare la cache in vendor/ e controlla che non ci sia anche  
un .bundle/cache nella root della app. quando mi capitato, ho risolto  
cos.
