quasar configured for scss, error on build

[asonis]

Hi Everyone,

I’m working for a company, and we are using quasar. I downloaded the latest version on quasar and I’m getting the following errors on the build

1st

2nd

the error comes out from a build on a docker environment (node:12.14.1)
what seems strange to me is that the complain is about the app.styl and the app.scss.

Then after different attempts, I found a solution on the extendWebpack.

// https://quasar.dev/quasar-cli/handling-webpack
      extendWebpack (cfg) {
        cfg.module.rules.push({
          enforce: 'pre',
          test: /\.(js|vue)$/,
          loader: 'eslint-loader',
          exclude: /node_modules/
        });
        cfg.module.rules.push({
          test: /\.scss$/,
          loader: 'sass-loader',
          exclude: /node_modules/
        });
      },

I have only a question: if we not specify a sass-loader (9.0.2) on the package.json, the build will fail?

Thanks a lot
Antonio
