You have already activated rake 0.8.7, but your Gemfile requires rake 0.9.2. Consider using bundle exec.

I Just moved to site 5 after creating my application offline. I am having problems with rake. When i try to run cd ~/MYAPP/; rake db:migrate --trace RAILS_ENV='production'

I get the following error

You have already activated rake 0.8.7, but your Gemfile requires rake 0.9.2. Consider using bundle exec.

When i try to unistall rake 0.8.7 I get the following warning. 

addressable-2.2.6 depends on [rake (>= 0.7.3)]
    execjs-1.2.6 depends on [rake (>= 0)]
    execjs-1.2.4 depends on [rake (>= 0)]

    thor-0.14.6 depends on [rake (>= 0.8)]
    treetop-1.4.10 depends on [rake (>= 0)]

I have seen a lot of articles about uninstalling one. When i remove rake 0.9.2 i get an error

no such file to load -- rake/dsl_definition

When already have the following in my rake file.

require 'rake/dsl_definition'
require 'rake'

Has anyone solved this problem, I have tried all too

You have already activated X, but your Gemfile requires Y

Try to run this command:

bundle exec rake db:migrate --trace RAILS_ENV=production

In this way you should launch your command with the pack of gem bundled with your app.
