Modern Front-End Development for Rails - application does not start after run bin/setup (page xviii)

After some hassle, I was able to finally run bin/setup, now I have started the rails server but I get this error message right when I visit the homepage:

ctionView::Template::Error (Webpacker can’t find application.css in /Users/thomas/Documents/Websites/rails-frontend/public/packs/manifest.json. Possible causes:

1. You want to set webpacker.yml value of compile to true for your environment
   unless you are using the webpack -w or the webpack-dev-server.
2. webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker’s config/webpacker.yml file.
4. Your webpack configuration is not creating a manifest.
   Your manifest contains:
