I added gem 'rails-observers' to my gemfile and I ran bundle install. I got

➜  test-gem bundle install

Bundler could not find compatible versions for gem "activemodel":

      activemodel (~> 4.0)

    web-console was resolved to 3.4.0, which depends on

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

For tried this I created a new rails project.

I changed the source in my gemfile to github and I install it!

gem 'rails-observers', :github => 'rails/rails-observers'

Yes, that is the only way to install it right now.
