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

It happens because you are using rake from the system. (latest version by default) The solution is use follow command:

bundle exec rake db:migrate

Also, you can create alias. Because this command is too big and difficult to write.

echo "alias be='bundle exec'" >> ~/.bash_profile
source ~/.bash_profile

Then you can use follow short command:

be rake db:migrate
