Error with Generate Scaffold Micropost

I'm following the http://ruby.railstutorial.org/ From my application directory I run this command but receive the error below. I have searched around but can figure out how to fix.

$ rails generate scaffold Micropost content:string user_id:integer

This is the error:

My routes.rb is:

DemoApp::Application.routes.draw do
  resources :users
  .
  .
  .
end

The key is in the first line of the error message.

/config/routes.rb:4: syntax error, unexpected '.' (SyntaxError)

Then in your routes file, notice that you have those periods, which do not belong.

DemoApp::Application.routes.draw do
  resources :users
  .
  .
  .
end

Remove the periods.

DemoApp::Application.routes.draw do
  resources :users
end
