Access denied for user 'root'@'localhost' (using password: NO)

i am using mysql db.

# Install the MySQL driver: # gem install mysql # On MacOS X: # gem install mysql -- --include=/usr/local/lib # On Windows: # gem install mysql # Choose the win32 build. # Install MySQL and put its /bin directory on your path.
