Process exited with code: 1
The error is pretty clear, line 3 in routes.rb contains the word route which is unexpected..
As discussed in comments, the line was
route 'pages#index'
This is not the correct syntax for defining root page, correct syntax is
root 'pages#index'
Refer 3.14 Using root here

Anybody knows how to fix it?
Maybe i should to do something more then only bundle. I am just starting, sorry if its to easy.
You are missing configuration variable(s) and the pusher initializer cannot read the url, because its missing an url. You see it this line from your backtrace:
from /Users/abdullahatkaev/the247clinic/config/initializers/pusher.rb:1:in `<top (required)>'
Check this file to see what you need exactly. It depends on your project how you can set the url. Either through rails or something like dotenv.

Did you added devise in routes.rb file? If you use devise for users, then you should have this line in your routes.rb
devise_for :user

Rails server exits on startup. (Rails 4.0.2)

Rails server suddenly keeps exiting on startup. Though it worked perfectly a little while ago. I haven't tweaked anything since.
=> Booting WEBrick
=> Rails 4.0.2 application starting in development on http: //0.0.0.0:3000
=> Run `rails server -h` for more startup options

As you can refer here..
Why is my development server not loading? default_controller_and_action': missing :action (ArgumentError)
It's because of syntax problem under config/routes.rb in your application:
Check your routes you may find like for example while defining controller#action in routes like below..
Syntax should not be like:
root :to => 'home/index'
Syntax should be like:
root :to => 'home#index'
