Active admin and devise gems are installed. The only problem is when I generate active admin. I use Rails-4.1.8 and ruby-2.1.4.

Thanks for help and good day.

You need to add the gem 'devise' to your Gemfile or directly using the cli

bundle add devise

or you need to run the install with the the --skip-users flag.

rails g active_admin:install --skip-users

activeadmin gem (I mean latest version of gem on rubygems.org) still is not compatible with Rails 4.x.

Try to use use latest version of activeadmin from repository:

gem 'activeadmin', github: 'activeadmin/activeadmin', branch: :master

I tried this, but it doesn`t work. Same error message. – projectxxx Feb 26 '15 at 19:50
It's very strange. I can't reproduce your problem. Could you please provide full backtrace? – Maxim Feb 26 '15 at 21:00
I reinstall my operation system and rvm two-three times, but not work. – projectxxx Feb 26 '15 at 22:52
Could you please provide your Gemfile? AA raise `DependencyError` exception if `devise` version isn't equal to ~> 3.2. May be you are using 3.1 for example. – Maxim Feb 27 '15 at 00:06
i tried to change devise version, but doesn`t work. I give you a link to pastebin with content to my Gemfile. http://pastebin.com/EWxfLBrv – projectxxx Feb 27 '15 at 07:55
Look at (this script)[https://gist.github.com/maxd/2cf74ef11e1f0c53d9cf]. It should create new Rails app, install all gems locally and install AA. Try to run it. – Maxim Feb 27 '15 at 09:46
Thanks, but the link is broken. Fix it please. – projectxxx Feb 27 '15 at 09:57
I remove rvm and install rbenv and everything is work. No idea what`s happening. – projectxxx Feb 27 '15 at 10:44
I have the same error. Gems are right. But getting this same dependency error. – Art Mar 04 '15 at 06:47
Use rbenv, that helps to me. – projectxxx Mar 06 '15 at 08:48
