After running the these three lines:
$ rails new MySite
$ bundle install
$ rails server
I tried viewing the Rails App in browser by clicking: http://localhost:8000.
But I get a message "Not Found" in the right side (browser side) of the screen.
Then, in the next step I ran this:
$ rails generate controller Pages
After rails generate finished running, the file pages_controller.rb was NOT created. I could not find it in app/controllers/pages_controller.rb.
Any ideas? I am stuck.
