Question

我正在尝试学习MEAN堆栈，并且在键入node start时遇到此错误

     npm ERR! code EJSONPARSE
    npm ERR! JSON.parse Failed to parse json
npm ERR! JSON.parse Unexpected string in JSON at position 489 while parsing 
npm ERR! JSON.parse   "name": "meanauthapp",
npm ERR! JSON.parse   "version": '
npm ERR! JSON.parse Failed to parse package.json data.
npm ERR! JSON.parse package.json must be actual JSON, not just JavaScript.

下面是我生成的package.json文件，并且没有使用npm init和npm install NAMES --save触摸过。我有一个app.js文件，可以将端口设置为3000，并将变量设置为我安装的必需软件包

  {
  "name": "meanauthapp",
  "version": "1.0.0",
  "description": "meanauthapp",
  "main": "app.js",
  "dependencies": {
    "bcryptjs": "^2.4.3",
    "body-parser": "^1.18.3",
    "cors": "^2.8.5",
    "ejs": "^2.6.1",
    "express": "^4.16.4",
    "jsonwebtoken": "^8.4.0",
    "mongojs": "^2.6.0",
    "mongoose": "^5.4.8",
    "passport": "^0.4.0",
    "passport-jwt": "^4.0.0"
  },
  "devDependencies": {},
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
    "start": "node app"
  },
  "author": "",
   "license": "ISC"
}

不确定输入错误的原因，谢谢！

您缺少逗号，因此无法解析无效的JSON。将您的脚本属性更新为：

"scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "node app"
  },

尝试键入“节点启动” MEAN堆栈时出错
