My solution

@import "../../../node_modules/spectre.css/src/variables";
@import "../../../node_modules/spectre.css/src/mixins/shadow";
@import "../../../node_modules/spectre.css/src/mixins/button";
@import "../../../node_modules/spectre.css/src/mixins/label";
@import "../../../node_modules/spectre.css/src/buttons";
@import "../../../node_modules/spectre.css/src/forms";
@import "../../../node_modules/spectre.css/src/labels";
@import "../../../node_modules/spectre.css/src/layout";

And needs to do picturepan2/spectre#694
