Bootstrap4-NPM启动报错

Question

我正在学习使用 npm 脚本自动执行 Web 开发任务。

下面是我的package.json:

{
  "name": "confusion",
  "version": "1.0.0",
  "description": "This is a website for Ristorante Con Fusion",
  "main": "index.html",
  "scripts": {
    "start": "npm run watch:all",
    "test": "echo \"Error: no test specified\" && exit 1",
    "lite": "lite-server",
    "scss": "node-sass -o css/ css/",
    "watch:scss": "onchange 'css/*.scss' --npm run scss",
    "watch:all": "parallelshell 'npm run watch:scss' 'npm run lite'"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
     "lite-server": "^2.2.2",
     "node-sass": "^4.7.2",
     "onchange": "^3.3.0",
     "parallelshell": "^3.0.2"
   },
   "dependencies": {
     "bootstrap": "^4.0.0-alpha.6",
     "font-awesome": "^4.7.0"
   }
}

但是，当我在命令提示符中运行 npm start时遇到以下错误：

错误信息：

我猜你正在使用 Windows。 Windows 命令行不喜欢 package.json 中的单引号。请改用 \"。

"watch:scss": "onchange \"css/*.scss\" -- npm run scss",
"watch:all": "parallelshell \"npm run watch:scss\" \"npm run lite\""

您还遗漏了 -- 和 npm 之间的 space。
