Motivation / Use-Case

#1002 was incomplete (I guess? because it wasn't working for me, and with this change it does).

With:

    "node-sass": "^7.0.0",
    "sass-loader": "^10.3.0",

Got error:

ERROR in ./app/app.global.scss (./node_modules/css-loader/dist/cjs.js??ref--8-1!./node_modules/sass-loader/dist/cjs.js!./app/app.global.scss)
Module Error (from ./node_modules/sass-loader/dist/cjs.js):
Node Sass version 7.0.1 is incompatible with ^4.0.0 || ^5.0.0 || ^6.0.0.

Note: I made the PR against branch v10. Not sure how to handle master. Please let me know how you'd prefer me to proceed, otherwise I'll let you handle it :)

The base branch was changed.

[snitin315]

Is this not working with the latest version v13 as well?

[julienma]

Don't know, I'm stuck on v10 due to other deps (mainly webpack 4).
