rake db:migrate is being aborted due to rake versi

Question

This question already has an answer here:

• You have already activated X, but your Gemfile requires Y 6 answers

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

just install old version by command: gem install rake -v '10.1.0'

Answer 2

I got this error message while deploying to production with capistrano. To fix it I executed the following on my production server:

gem update rake

Answer 3

I had the same error but running bundle update rake didn't work for me. This answer worked for me. You have to remove your Gemfile.lock:

rm Gemfile.lock

then re-bundle:

bundle install

Answer 4

I got the answer. Why we got this error? For the rake version of our OS is different from the version of our project. When we set the same. Everything gets ok!

The light way is set the same version in our Gemfile. And make sure keep all the project the same rake!

gem 'rake', '10.2.2' #forking error! force the version the same with our OS and all projects!!!

I hope U see what I said and the real reason of this error. Then we will have more resolutions such as "bundle update rake". Thanks!

Answer 5

You want to use bundle exec:

bundle exec rake db:migrate

Or, if you're using Rails 4 binstubs:

./bin/rake db:migrate

Answer 6

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

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