Rake aborted! no such file to load --bundler/setup Rails 3.1

Question

I am very new in Rails. after I created a new rails project.

rails new test project

I ran

rake db:create 

In

Answer 1

Got the same missing bundler message running rake after upgrading to Ruby 1.9.2.

Rake needed updating and bundler needed to be reinstalled:

sudo gem update rake

sudo gem install bundler

Reinstalling bundler might have fixed the error, but you want to make sure rake is right too.
