[NODEMON]-无法将babel-node识别为内部或外部命令 [英] [NODEMON]- babel-node not recognized as internal or external command

问题描述

我正在尝试设置一个简单的快递服务器.我正在使用nodemon启动我的开发服务器，但我的应用不断崩溃，因为它无法识别"babel-node"节点.命令.

I am trying to setup a simple express server. I am using nodemon to start my development server But my app keeps crashing because it does not recognize the "babel-node" command.

错误输出是

[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

my package.json scripts are

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

我的依赖项和开发者的依赖项是

and my dependencies and dev dependencies are

"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"
  }

我尝试通过使用常规的node命令在没有nodemon的情况下对其进行测试，并且它按预期运行

I tried testing it without nodemon, by using the regular node command and it runs as expected

$ npm run start

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

Server is up...

我的文件夹strucher在下面

My folder strucher is below

在此处输入图片描述

index.js的内容是

the contents of index.js are

const express = require("express");


const app = express();

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

我也尝试过删除node_modules和package-lock.json文件并重新安装，但仍然崩溃.

I have also tried deleting my node_modules and package-lock.json files and reinstalling but still crashes..

(*这是我的第一个问题;))

(*this is my first question ;) )

推荐答案

删除您的node_modules并按照以下步骤操作:

Remove your node_modules and follow these steps:

 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:

Then, check the existence of these files:

node_modules/.bin/babel-node

node_modules/.bin/babel-node

node_modules/.bin/babel-node.cmd-仅Windows

node_modules/.bin/babel-node.cmd - windows only

node_modules/@babel/node/bin/babel-node.js

node_modules/@babel/node/bin/babel-node.js

如果一切正常，请添加到package.json:

If everything looks good add to package.json:

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