When trying to migrate my db using rake I get the following error message:
rake aborted! No migration with version number 3
I am using sqlite3 as my database server. Any help is much appreciated.
mpls, If you are running rails prior to Rails version 2.0, it means that you do not have a file like: db/migrate/003_....
Thanks for the reply. I am using rails 2.0 and the migration file is prefixed with 20080827011222_ When I run the following command: rake db:migrate I get the rake aborted! No migration with version number 3. but when I run: rake db: migrate version 0 the table is created. How do I make rake db:migrate work so I can have version beyond 0. Thanks

Also why is the version number 3 when this is the first time I ran rake db:migrate.
