Answer 1

sudo apt-get install --assume-yes mysql-server-5.1 mysql-client-5.1 libmysqlclient-dev 

Cela devrait être tout ce que vous avez besoin pour le petit bijou de mysql2.

Answer 2

Je suppose que vous êtes sur OS X basé sur votre répertoire personnel étant/Users/yozloy. Avez-vous installé le xcode developer tools? Ce paquet est requis pour compiler certaines gemmes.

Answer 3

Merci Mike .. Il fonctionne pour moi :) J'utilise Ubuntu, installé juste

apt-get install --assume oui mysql-server-5.1 mysql-client-5.1 libmysqlclient-dev

et a travaillé pour moi.
