rake db:migrate is being aborted due to rake version difference

Question

I am getting the error

rake db:migrate --trace
rake aborted!
You have already activated rake 10.1.1, but your Gemfile requires rake 10.1.0. Using bundle exec may solve this.

used bundle and it did not fix the problem... any ideas as to help fix this problem?

Answer 1

I hit the same error. Running bundle update solved it.

Update: As suggested by TuK bundle update rake is the way to go.
