Error installing devise for rails4 - ruby-on-rails

I'm trying to migrate an existing app to ruby 2.0 + rails 4.0 and so far everything is working except that when I try to install devise:
rails generate devise:install
I get the following error:

I get the same error when I try to run the app just doing bundle install and then rails s.
Any idea?
Thanks!

[UPDATE]
The rails4 branch has now been merged into master. So this should be all you need now:
gem 'devise', github: 'plataformatec/devise'
I've left my old answer below.
================================================
The easiest fix today is to use the following in your gemfile:
gem 'devise', github: 'plataformatec/devise', branch: 'rails4'
More details can be found on the comment of this pull request for Devise.
At the time of Lemurido's response, his was the best solution to your error.

This seems to be a dependency issue, as explained by Aaron Paterson:
http://tenderlovemaking.com/2012/12/18/rails-4-and-your-gemfile.html
The solution (in the comments) is updating your gemfile with:
gem 'devise', github: 'idl3/devise', branch: 'rails4'

I google these error but it seems code error however i have not written any code in newly created project just trying to install active admin for practise.
Please help me to sort this out.
This is due to a recent bug. Just use the latest version from RubyGems, not GitHub. If you omit inherited_resources from your Gemfile this should be done for you by default.
Here is what I would use in my Gemfile:
gem 'activeadmin', github: 'activeadmin'
gem 'inherited_resources'
Looking at 'inherited_resources' github repository, it looks likes the current version in the repo is broken. As a best practice try to use versions of gem that you can control (the call above is not even really clean for a production app)
You may also fall on some SSL error after so to fix this, just add the following to your Gemfile
gem 'openssl', '>=2.0.3'

But the actual problem is just my commented " #gem 'pg' " in gemfile. Im using latest LTS Ubuntu, ruby 2.3 and rails 4.2
I found solution to this issue. I open bashrc(shell startup configuration file) in terminal
nano ~/.bashrc
and cut
export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"
export PATH="$HOME/.rbenv/bin:$PATH"
then I save changes and exit (ctrl+O enter ctrl+X).
And the long output is gone.

omniauth facebook uninitialzed constant error

I am following the rails cast video here but when I try run my server I am getting a error "uninitialized constant OmniAuth (NameError)". When I remove this file the server starts and the home page is shown except the link to facebook login authentication returns a routing error "No route matches [GET] "/auth/facebook" of course.
My question is similar to this stackoverlfow question here but mine is in development mode.
All code is the same I am wodnering what this is. Please help!
Full error is

Also if the /initializers/omniauth.rb is in its folder I cannot generate the user model I need to remove it to even do this?
I have the latest version of omniauth-facebook gem installed and ran bundle install.
do you have both omniauth and omniauth-facebook in your gemfile? like:
gem 'omniauth'
gem 'omniauth-facebook'

it looks like you are running simple_form 1.4.1 try upgrading it to the latest version. which should work with rails 4. if you are specifying a version in your Gemfile remove the version tag, and run bundle update
Give this a go gem 'simple_form', :git => 'git://github.com/plataformatec/simple_form.git'. I think you need a more recent version of simple_form.

Rails server not starting - rails 4.0.0.rc1

I am following the tutorial on http://ruby.railstutorial.org/ and now I am not able to start the server. In my gemfile I am using ruby 2.0.0 and rails 4.0.0.rc1 - then I tried changing back to ruby 1.9.3 and rails 3.2.13 - still not working
this is what terminal tells me:

Do you have any initialisers or lines in config files that make a call to a FourTest class? Because that class can't be found. Start by searching your code for FourTest then check that you've followed naming conventions on the file that contains the class and that it's in a folder that gets loaded by default (models folder) or that you are manually loading it before using it (lib folder, etc).
