laravel-mix: v 0.8.7 - mix.sass().options() - Module build failed: Error "...scss" is not in the SourceMap

Same, when I set to mix.options({ processCssUrls: false });

Then the error appear.

But after I add below to package.json it SOLVED.

"resolve-url-loader": "^2.0.0", "sass-loader": "^6.0.0",

Looks like we needed to bump sass-loader and resolve-url-loader dependencies to fix this. I’ve pushed and tagged it.

@coder77 save my day! Thanks!

@coder77 Thank youuu!!! It worked!

Tested it with a fresh installation of Laravel, also returns this error.

node -v v7.7.1 npm -v 4.1.2

Create fresh Laravel installation composer create-project --prefer-dist laravel/laravel mix-test

Install node modules npm install

Run npm run dev

No errors

Disable processCssUrls mix.options({ processCssUrls: false }); Returns error:
