http://localhost:300x/shopping_cart/show it gives me default error ""We're sorry, but something went > wrong.We've been notified about this issue and we'll take a look at it shortly.""

you should only see that if you're running in production mode -- there's
a "development" mode for a reason :slight_smile:

So do you have the mysql gem installed? For that matter, do you
have mysql installed?

Looks like you're running Windows, so I can't help much with the
details. Probably your best bet is to google "rails windows mysql"
and take your pick of the suggestions.

HTH!
