「couldn't find file 'third_party/xxxxxxxx.min.js' with type 'application/javascript'」

ENVIRONMENT

Rails 5.2.1

ruby 2.4.2

wysiwyg-rails 2.6.6

froala-editor-sdk 1.2.0

ERROR

(app/assets/javascripts/application.js)

...
//= require third_party/spell_checker.min.js
//= require third_party/font_awesome.min.js
//= require third_party/embedly.min.js
//= require third_party/image_tui.min.js

@import 'third_party/embedly.min.css';

SOLUTION

1. update gem wysiwyg-rails version

wysiwyg-rails (2.6.6) -> wysiwyg-rails (2.9.6)

two impotant things

・wysiwyg-rails (2.6.6) is not supporting third party except spell_checker.

・version of wysiwyg-rails must not exceed 3.0 because of dependency with froala-editor-sdk.

2. chenge from font-awesome-sass to font-awesome-rails

・add gem 'font-awesome-rails' in Gemfie

・bundle install

・add @import 'font-awesome'; in (app/assets/stylesheets/application.scss)

3. Reboot Rails Server

4. access webpage

you'll confirm alll third party work well !! COOL    

For everyone, I'll share my application.scss and application.js
