You have already activated rake 10.0.4, but your Gemfile requires rake 10.0.3.

I'm careful to create separate gemsets for each project, so when I run bundle install, it only installs gems for that gemset. This way gems dont creep into the wrong projects. Now I just pulled a project from github. I made sure I was in the correct gemset, and then I run bundle install and it works fine. but then when I use rake to create the database "rake db:create". I get this error:

You have already activated rake 10.0.4, but your Gemfile requires rake 10.0.3.

What does it mean "you already activated rake 10.0.4"? All that should be installed for this gemset is whatever is in Gemfile.

Did you declare rake in your Gemfile? Also, did you try bundle exec rake db:create?

I think maybe rake is loaded before your gemset has a chance to assert itself.

I guess you have installed rake in your global gemset for the ruby version you are using. Go outside the project and run rvm use <ruby version>@global and then gem list. If you see rake in the list, that means you have it in the global gemset. No matter which gemset you use with the ruby version, the gems in the global gemset will be available.

Bundler is present in the global gemset. What I usually do is rvm gemset use @global and then do a gem uninstall bundler
