rake aborted! You have already activated rake 10.0.2, but your Gemfile requires rake 0.9.2.2

Question

I am trying to do \"rake db:migrate\" and it is giving me this error.

Andy:AcademyAir Andy$ rake db:migrate
/Users/Andy/.rvm/gems/ruby-1.9.2-p290/gems/bundler-1.         


        

Answer 1

I've just ran into the same problem.

1. I inserted in my gemfilen gem 'rake', '~> 10.0.1' [in your case it should be '10.0.2']
2. I deleted my gemfile lock
3. I ran rake db:migration again and it worked.

I got this tip here: Activated Ruby RAKE 10.0.1, require 10.0.0

Update: In my case I didn't have rake duplicated. I just have in my gems the 10.0.1 version.
