Hello Avinash, Did you install do_sqlite3 and dm-sqlite-adapter? I wonder what tutorial you are following, since sqlite3-ruby isn't needed nor used with DataMapper. If that is mentioned in the tutorial, we should see if we can fix that, since it's not needed and can lead people onto the wrong path.
Could you try again after installing do_sqlite3 and dm-sqlite-adapter? -- Regards, Dirkjan Bussink On 31 Aug 2010, at 01:00, [email protected] wrote: Hey, I have been going through a Sinatra tuorial and trying to get the DM gem to work all morning and havent got very far, any help or pointers is greatly appreciated!!
