typusの導入方法

Question

###わからないこと
railsでtypusを使いたくて、

<Gemfile> ``` gem 'typus' ``` ``` $ bundle install --without production ```

としましたがエラーが出ました。

$ rails g typus
/home/vagrant/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/actionpack-5.0.0.1/lib/action_dispatch/routing/mapper.rb:78:in `check_via': You should not use the `match` method in your router without specifying an HTTP method.
If you want to expose your action to both GET and POST, add `via: [:get, :post]` option.
If you want to expose your action to GET, use `get` in the router:
  Instead of: match "controller#action"
  Do: get "controller#action" (ArgumentError)

こちらのやり方でもやってみましたが、ダメでした。

gem 'typus', git:"https://github.com/typus/typus.git"

###その他

Rails.application.routes.draw do
  get 'sessions/new'

  root 'static_pages#home'
  get    '/help' => 'static_pages#help'
  get    '/about' => 'static_pages#about'
  get    '/contact' => 'static_pages#contact'
  get    '/signup' => 'users#new'
  get    '/login' => 'sessions#new'
  post   '/login' => 'sessions#create'
  delete '/logout' => 'sessions#destroy'
  resources :users
  resources :accout_activations, only: [:edit]
end

###追記

なぜかサーバが立てれなくなっています。

$ rails s -b 0.0.0.0
=> Booting Puma
=> Rails 5.0.0.1 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
