React 中使用sass

npm install node-sass-chokidar --save-dev

package.json添加两行：

1    "scripts": {
2      "build-css": "node-sass-chokidar src/ -o src/",
3      "watch-css": "npm run build-css && node-sass-chokidar src/ -o src/ --watch --recursive",
4      "start": "react-scripts start",
5      "build": "react-scripts build",
6      "test": "react-scripts test --env=jsdom",

运行 npm run watch-css 会将src目录下的scss转换成css
