Background

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

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):

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?

Did you do what the error suggests: npm rebuild node-sass?

Running that fixed one of the errors, but now I get another one:

I would advise You to replace node-sass, by sass…

Remove “node-sass”: “^4.13.1”

(npm uninstall …)

Add sass

npm i -D --prefix assets/ sass

If you cd assets then you don’t need the --prefix assets flag.

This is the solution that fixed the issue.
Thanks !

If I may ask, why did you advised this course of action?

Because node-sass has been a real burden for Phoenix Team Core members when version broke the asset pipeline.

https://github.com/phoenixframework/phoenix/issues/4126

Not only this, but node-sass might be the main reason why Phoenix moved to esbuild :slight_smile:
