无法运行npm start：无法GET /

Question

当我尝试使用“ npm start”运行网站时，它仅显示以下内容：无法获取/。

这是我的package.json文件：

{
  "name": "assignment1",
  "version": "1.0.0",
  "description": "This is a website for Ristorante Con Fusion",
  "main": "aboutus.html",
  "scripts": {
    "start": "npm run lite",
    "test": "echo \"Error: no test specified\" && exit 1",
    "lite": "lite-server"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "lite-server": "^2.5.4"
