    ActiveAdmin with Rails 4 requires you to track master. From the github page:

    We're currently working on 1.0.0, which as far as dependencies, moves us from meta_search to Ransack and adds Rails 4 support. You can get Rails 4 and 4.1 support by tracking master:

    gem 'activeadmin', github: 'gregbell/active_admin'

    Also, make sure you DON'T use the docs on the main page because they are outdated for rails 4. There are updated docs for rails 4 with master.

    I'm not sure how much longer this answer will be relevant, so you should check github to see if things have changed before blindly tracking master. Also, note that tracking master usually means you will get development changes as they come.

    If you changed your rails to 3.2.13 then also change your active support in the gemfile.lock to 3.2.13 then:

    Run:

    $ bundle update

    shut down your server:

    $ control c

    Make sure in your terminal that you are in your project folder then: restart your server:

    $ rails server

    refresh your browser

    For anyone who accidently comes to this link (at the time google served this page first); check out this post Bundler could not find compatible versions for gem, updating Rails app

    My steps were run

    gem update rails
    
    rm Gemfile.lock
    

    change my Gemfile to reference the version of rails i wanted

    gem 'rails', '3.2.13'
    

    finally run

    bundle install 
    

    I didn't try bundle update as @PistachioPony suggested but that might take the place of removing the lock file and rebuilding.
