Background

I am trying to run the demo app desktop-example-app showed in Elixir Berlin meetup February 2021:

• https://www.youtube.com/watch?v=aFpBHQ0YEw4&t=2016s
• GitHub - elixir-desktop/desktop-example-app: Elixir Sample App using the Desktop library with LiveView to create a desktop app · GitHub

I can launch the application, however when it opens it keeps crashing.

Problem

While it keeps erroring out I have noticed the following error:

ERROR in ./css/app.scss
Module build failed (from ./node_modules/mini-css-extract-plugin/dist/loader.js):
ModuleBuildError: Module build failed (from ./node_modules/sass-loader/dist/cjs.js):

This usually happens because your environment has changed since running `npm install`.
Run `npm rebuild node-sass` to download the binding for your current environment.

What I tried

So, to fixed this I did:

• cd assets
• npm install --save --prefix assets mdn-polyfills url-search-params-polyfill formdata-polyfill child-replace-with-polyfill classlist-polyfill new-event-polyfill @webcomponents/template shim-keyboard-event-key core-js
• npx browserslist@latest --update-db
• cd ../
• mix phx.digest

And the I run it normally: ./run

Question

I believe I have following every instruction, however I still cannot get the app to work.
What am I doing wrong?
