ciao a tutti utenti del forum! questo è il mio primo topic 
allora devo installare la gem per usare ruby insieme a Mysql,ma quando
accedo al terminale e inserisco il comando mi compare il seguente
messaggio di errore:
Error loading RubyGems plugin

no such file to load – rubygems_bundler/rubygems_bundler_installer
(LoadError)
e poi…
Building native extensions. This could take a while…

Gem files will remain installed in
/usr/local/rvm/gems/ruby-1.9.2-p318/gems/mysql-2.8.1 for inspection.
Results logged to

qualcuno mi può gentilmente aiutare? Sono alle prime armi sia con ruby
che con mysql magari è un errore da poco.
vi ringrazio anticipatamente.
