Have you tried to use sass instead of node-sass?

Actually, there's a note about this issue in Vue CLI docs:

When using webpack version 4, the default in Vue CLI 4, you need to make sure your loaders are compatible with it. Otherwise you will get errors about confliciting peer dependencies. In this case you can use an older version of the loader that is still compatible with webpack 4.

npm install -D sass-loader@^10 sass

I also got this error when install sass-loader. Fix it by the reference here: https://github.com/laravel-mix/laravel-mix/issues/2562

Need to add --legacy-peer-deps to resolve it. enter image description here

I had the same problem today. Try installing sass-loader v10.0.5 instead:

npm install -D [email protected] node-sass
