node-sass 설치시 오류 - Build failed with error code: 1

$ npm init react-app test-app

리액트 프로젝트를 생성하고..

$ npm install node-sass@4.14.1 classnames react-icons --save-dev

위 명령어를 실행해서 node-sass 외 2개의 패키지를 설치하려고 했는데,

PS C:\dev\todo-app> npm install node-sass@4.14.1 classnames react-icons --save-dev

이런 에러가 발생했다. python 어쩌구 에러가 떠서 착각할 수 있는데, 결론적으로 4.x 버전대의 패키지 빌드를 최신 버전의 npm에서 정상적으로 수행하지 못해서 발생하는 것 같다.

$ npm install node-sass@6.0.1 classnames react-icons --save-dev

위와 같이 node-sass 버전을 6.x 이상으로 설치해서 해결했다.
