【Ruby on Rails】ブラウザにてアラートダイアログを表示させたい

実現したいこと

某参考書にてRuby on Railsを勉強しております。
ブラウザにてページを読み込むとアラートが表示されるとのことなのですが、下記のようなエラーが出てしまい実行されません。

参考書やインターネットにて調べたのですが、解決方法が見つからなかったため質問いたしました。
もし可能でしたら修正点などご教示いただけますと幸いです。

試したこと

下記の質問者様同様、アプリを新規作成した際「user.coffee」ファイルが見当たらなかったため、自作しました。

調べたところ、起動エラーとのことなのですが、下記を実施した際も変わらずでした。
どなたかお分かりでしたらご教示いただけますと幸いです。

views/users/index.html.erb に
<%= stylesheet_link_tag 'users' %> <%= javascript_include_tag 'users' %>
とあるのが　？？です。
一般的には rails new するとできている views/layouts/application.html.erb に <%= stylesheet_link_tag 'apllication' %> と書かれていて、それを使うのですが。
