我有一个这样的JSON文件

{
  "name": "Loopstudios",
  "version": "1.0.0",
  "description": "Loopstudios webpage",
  "main": "index.js",
  "scripts": {
    "watch:sass": "sass sass/main.scss css/style.css -w",
    "devserver": "live-server --browser=firefox",
    "start": "npm-run-all --parallel devserver watch:sass",
    "compile:sass": "sass sass/main.scss css/style.comp.css",
    "prefix:css": "postcss --use autoprefixer -b \"last 10 versions\" css/style.comp.css -o css/style.prefix.css",
    "compress:css": "sass css/style.prefix.css css/style.css --style compressed",
    "build:css": "npm-run-all compile:sass prefix:css compress:css"
  },
  "author": "Utku",
  "license": "ISC",
  "devDependencies": {
    "autoprefixer": "^7.1.4",
    "concat": "^1.0.3",
    "npm-run-all": "^4.1.1",
    "postcss-cli": "^4.1.1",
    "sass": "^1.32.12"
  }
}

当我运行build：css时，它会给我一行CSS代码，如下所示

以前它给出了几行代码，但现在所有的代码都卡在一行中。这是为什么？它还给出了两个。map文件是那么正常，在我看来是没有必要的。
我想要这样的
