rake db:migrate debacle

Hi there - I’m a ruby newbie and am stuck on the Getting Started with Rails app. See output below. Problem arose when I ran the rake db:migrate command. I also tried the ‘rake db:migrate RAILS_ENV=development’ command which may be obvious. Any ideas on how to fix this?

Many thanks!!

Hi there - I'm a ruby newbie and am stuck on the Getting Started with Rails

Fix what?

ActiveRecord::PendingMigrationError (Migrations are pending; run 'rake
db:migrate RAILS_ENV=development' to resolve this issue.):

So you stop the server, run the migration(s) -- and then what?

I think you need to run the “rake db:migrate”

Did the db:migrate operation complete successfully? Verify using the command line tool appropriate for the database manager you’re using. What step are you at in the Getting Started Guide?
