I am using windows and a main.scss importing a ./mixin/sub.scss

then:

import * as SassCompiler from './sasslib/sass.node.js';

SassCompiler(pathtoScss, { ... }, r => {
  if (r.status) { console.log(); process.exit(99); }
});

It tells me, it doesn't find my sub.scss - even thought, showing me the correct full path. I am trying to add this in a small company internal extension for VSCode.

Any additional step needed?

edit:

(without a hack like process.chdir( '.' + pathtoScss.replace(path.dirname(pathtoScss) )) ? This would be kinda problematic with other extensions. And the Editor.)

edit2:

there seems to be a solution (somehow not really understandable to me) at https://github.com/ritwickdey/vscode-live-sass-compiler/blob/3d2818d9053454affeab2e6fce4a7beb7c36cfb5/src/appModel.ts#L172
