[pjaer]

any solution on this issue?

Worked for me to update loader(s) to latest versions

[akerdi]

solved by downgrade sass-load to 7.1.0, worked piece:

sass-loader: 7.1.0
webpack: 3.6.0
vue-loader:  13.3.0
vue: 2.5.2

[realtebo]

I solved upgrading vue-loader to ^15.7.1 and removing explicit declaration of css-loader dependency.
Also, webpack is not explicited, but actually is being resolved as webpack@^4.27.1.

Note I'm using yarn
