Salve a tutti.Ho comprato “Learn to program” di Chris P. e tratta come
imparare a programmare con ruby. Mi sto scrivendo anche un manuale con
le
cose principali di ruby, ma incontro difficoltà con i metodi.
Ok, eccetto questo sto, mi sono scaricato ed installato ruby184-20.exe
ma
non so come avere la libreria per creare uno script che si colleghi a
sqlite. Uso il programma gem, ma ottengo il seguente errore.
Grazie.
