Salve, sono disperata…ho installato ruby on rails in ubuntu da pochissimo (grazie sopratutto al vostro aiuto). Ora che ho tutto installato e creato anche applicazione, ecc ho problemi nel creare i db (rake db:create), penso avere problemi con la gem mysql che non ho installato (gem list…non compare)…cerco di installarla ma mi da errore (vedere qui sotto), è tutto il pomeriggio che cerco in internet ma penso di avere dei casini…cerco “mysql\_config” nel mio sistema con “locate mysql\_config” e il percorso è “/opt/lampp/bin/mysql\_config”, premetto che ho anche installato xampp per favore aiutatemi, grazie * * * ~# sudo gem install mysql – --with-mysql-config=/usr/bin/mysql\_config Building native extensions. This could take a while… ERROR: Error installing mysql: ERROR: Failed to build gem native extension. /usr/bin/ruby1.8 extconf.rb --with-mysql-config=/usr/bin/mysql\_config extconf.rb:10: command not found: /usr/bin/mysql\_config --cflags \*\*\* extconf.rb failed \*\*\* Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.
