When generating toy\_app using scaffolding I can go to the root site using the local server, but when I try to go to the page /users I get the following error message: "Errno::ENOENT in UsersController#index"

The page should allow me to enter a new user. 

When I try to restart the server and run `rails server -b $IP -p $PORT`I get the following:

```
