I have problem with ActiveAdmin. I've added the gem 'activeadmin' to my Gemfile and ran

$ bundle install

which worked. But when I try to: 

$ rails g active_admin:install

I get:

/home/dominika/active_admin/config/application.rb:10:in `<module:ActiveAdmin>': superclass mismatch for class Application (TypeError)
from /home/dominika/active_admin/config/application.rb:9:in `<top (required)>'

from -e:1:in `<main>'

Maybe it's really stupid, but I really don't know how to fix it. Please, help...

This happens because your application is called active_admin. Rename it, and everything will work.

To rename the app view this thread to get the instructions.

Overall it sounds like you are pretty much doing things correctly.

I've added the gem 'active_admin'

From the documentation it's:

# Gemfile

gem 'activeadmin'

Does that help?
