При установке SCSS в проект Vue происходит синтаксическая ошибка, как исправить?

С помощью Vue-CLI разворачиваю проект. Все норм.
Устанавливаю pug (npm install -D pug pug-plain-loader). Все норм. Поддерживается синтаксис pug в .
Затем устанавливаю scss (npm install -D sass-loader node-sass). Руководствовалась этой статьей. Все нормально до того момента, как я пытаюсь его использовать так:
<style lang="scss">
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

Вот ошибка при пересборке проекта:
ERROR  Failed to compile with 1 errors                                                                                                                                                  15:22:19

Возможно, нужно что-то еще прописать в файл конфигурации webpack?
Файл конфигурации webpack.base.conf.js:

Подскажите, в чем проблема? Уже замучалась, проблема повторяется неоднократно.

P.S.:
после удаления Node.JS (удалила версию установленную НЕ через nvm), ошибка поменялась. Теперь ругается:
