Nodemon, babel-node 不是內部或外部命令，也不是可運行的程序 或批處理文件

Question

我一直在嘗試使用npm start本地主機，但在終端中出現此錯誤：

[nodemon] 2.0.4
[nodemon] to restart at any time, enter `rs`
[nodemon] watching path(s): backend\**\*
[nodemon] watching extensions: js,mjs,json
[nodemon] starting `babel-node backend/server.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...

根文件夾中的package.json為：

{
  "name": "abc",
  "version": "1.0.0",
  "description": "ABC",
  "main": "index.js",
  "scripts": {
    "start": "nodemon --watch backend --exec babel-node backend/server.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "cors": "^2.8.5",
    "express": "^4.17.3"
  },
  "devDependencies": {
    "@babel/cli": "^7.10.3",
    "@babel/core": "^7.10.3",
    "@babel/node": "^7.10.3",
    "@babel/preset-env": "^7.10.3",
    "nodemon": "^2.0.4"
  }
}

我在 node_modules 中也有這些文件。

• node_modules/.bin/babel-node

• node_modules/.bin/babel-node.cmd

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

我剛開始在節點中工作，不知道如何解決這個問題。 提前致謝。

嘗試這個

1. 刪除 package-lock.json
2. 刪除文件夾 node_modules 及其所有內容
3. 安裝全局babel節點：npm install -g @babel\node
4. 重新安裝所有軟件包：npm install
5. 重新啟動您的應用程序：npm 開始
