Rails 3 migration error

Question

I am new to Ruby and Rails, and whenever I attempt to generate my database using rake db:migrate I get the following error:

rake aborted! You have already activated rake 0.9.3.beta.1, but your Gemfile requires rake 0.9.2. Consider using bundle exec.

I am using Ruby 1.9.2 and Rails 3.

Answer 1

Consider using bundle exec.

There's your clue. Try this instead:

bundle exec rake db:migrate
