Я использую nodemon, чтобы начать пример с hello world в приложении React Native. Но мое приложение продолжает сбой, потому что оно не распознает команду «вавилонский узел», когда я выполняю «npm run dev». Вывод ошибок является:

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

Как исправить эту ошибку?

Мой пакет.json:

 {  "name": "frontend",  "version": "1.0.0",  "main": "index.js",  "scripts": {  "build": "babel src -d dist",  "dev": "nodemon src --exec babel-node"  },  "keywords": [],  "dependencies": {  "@babel/plugin-proposal-class-properties": "^7.16.0",  "@babel/plugin-proposal-private-property-in-object": "^7.16.0",  "@react-native-community/masked-view": "^0.1.11",  "@react-navigation/native": "^6.0.6",  "@react-navigation/stack": "^6.0.11",  "cors": "^2.8.5",  "dotenv": "^10.0.0",  "express": "^4.17.1",  "morgan": "^1.10.0",  "mysql2": "^2.3.3",  "native-base": "^3.2.1",  "radio-buttons-react-native": "^1.0.4",  "react": "17.0.1",  "react-dom": "17.0.1",  "react-native": "^0.64.2",  "react-native-animatable": "^1.3.3",  "react-native-dropdown-picker": "^5.1.21",  "react-native-gesture-handler": "^1.10.3",  "react-navigation": "^4.4.4",  "react-navigation-shared-element": "^3.1.3",  "react-navigation-stack": "^2.10.4",  "styled-components": "^5.3.3",  "styled-system": "^5.1.5",  "swagger-jsdoc": "^6.1.0",  "swagger-ui-express": "^4.2.0"  },  "devDependencies": {  "@babel/cli": "^7.16.0",  "@babel/core": "^7.16.0",  "@babel/node": "^7.16.0",  "@babel/plugin-proposal-private-methods": "^7.16.0",  "@babel/preset-env": "^7.16.4",  "@babel/register": "^7.16.0",  "babel-core": "^7.0.0-bridge.0",  "nodemon": "^2.0.15"  },  "private": true }  

Мой index.js (в папке src: src/index.js):

 const greet = 'hello world' console.log(greet)  

Мой архив .babelrc:

 {  "presets":[  // "@babel/preset-env"  ["@babel/preset-env", { "loose": true }]  ],  "plugins": [  ["@babel/plugin-proposal-class-properties", { "loose": true }],  ["@babel/plugin-proposal-private-methods", { "loose": true }],  ["@babel/plugin-proposal-private-property-in-object", { "loose": true }]  ] }  

Прежде всего, Спасибо

Решение, которое сработало для меня, было удалить package-lock.json и запустить: npm install @babel/node-g. 🙂
