Using a later version of rails (5.2.3) I found that the instructions given in the book didn't work. The console warned me that jQuery needed to be installed, and by going to https://github.com/rails/jquery-rails I was able to find the instructions to get it up-and-running.

Add to the Gemfile:

gem 'jquery-rails'

Add to application.js

//= require jquery
//= require bootstrap

So that the whole Gemfile is

//= require rails-ujs
//= require activestorage
//= require jquery
//= require bootstrap
//= require turbolinks
//= require_tree .
