[NODEMON]-babel-node不能识别为内部或外部命令

Question

错误输出为

[nodemon] 2.0.7
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): *.*
[nodemon] watching extensions: js,json
[nodemon] starting `babel-node index.js`
'babel-node' is not recognized as an internal or external command,
operable program or batch file.
[nodemon] app crashed - waiting for file changes before starting...

我的package.json脚本是

"scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "startdev": "nodemon --ext js,json  --exec babel-node index.js",
    "start": "babel-node index.js"
  }

我的依赖项和dev依赖项是

"dependencies": {
    "express": "^4.17.1",
    "express-graphql": "^0.12.0",
    "graphql": "^15.4.0",
    "uuid": "^8.3.2"
  },
  "devDependencies": {
    "@babel/cli": "^7.12.10",
    "@babel/core": "^7.12.10",
    "@babel/node": "^7.12.10",
    "@babel/plugin-proposal-object-rest-spread": "^7.12.1",
    "@babel/preset-env": "^7.12.11",
    "nodemon": "^2.0.7"
  }

$ npm run start

> dev_forum@1.0.0 start
> babel-node index.js

Server is up...

const express = require("express");


const app = express();

app.listen(() => {
    console.log("Server is up...")
})

删除node_modules并执行以下步骤：

 npm install --save-dev @babel/core @babel/cli @babel/preset-env @babel/node

然后，检查这些文件是否存在：

node_modules/.bin/babel-node

"start": "nodemon --exec babel-node index.js",
