Привет. Есть компонент App.vue. Внутри него объявлен стиль scss:

.roboto-text {
font-family: Roboto;
font-style: normal;
font-weight: 500;
}

<template>
<v-app>
<div>
<Head/>
</div>
</v-app>
</template>

Есть компонент Head.vue. Я хочу сделать extened этого стиля внутри него:

<style scoped lang="scss">

.user-info {
padding-top: 0;
@extened .roboto-text;
}
</style>

Этот стиль не экстендится. Почему?

Module build failed (from ./node_modules/sass-loader/dist/cjs.js):
SassError: The target selector was not found.
Use "@extend .roboto-text !optional" to avoid this error.
