rake aborted! You have already activated rake 10.0.2, but your Gemfile requires rake 0.9.2.2
rake, ruby-on-rails
Solution
Try this `bundle exec rake db:migrate`
Remove rake 10.0.2 gem
By using `gem uninstall rake` and remove `10.0.2` version of rake gem
And Then Try `rake db:migrate`
Why Error comes : In you gem list two version (10.0.2 and 0.9.2.2) of rake gem install so that this error comes.*
Another Solution is you can do `bundle update`
Problem
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-1.2.2/lib/bundler/runtime.rb:197: warning: Insecure world writable dir /usr in PATH, mode 040777 rake aborted!
