I have a ROR app where I have installed toaster and jQuery using yarn: yarn add jquery ; yarn add toastr. Also add their configuration to application.js:
// app/assets/application.js
//= require jquery
//= require rails-ujs
//= require activestorage
//= require turbolinks
//= require toastr/toastr
Also update application.scss:
app/assets/stylesheets/application.scss
@import "toastr/toastr";
App tested locally and work good. But when I try to push it to Heroku I got this error:
remote: Running: rake assets:precompile

What do I need to do for fix that ?
The best way is to use elements.heroku.com/buildpacks/yarnpkg/yarn this yarn build pack in Heroku and precompile all asset before pushing to Heroku and if that not work for you please continue to use this gem github.com/tylergannon/toastr-rails
