How to fix npm ERR! missing script: start in react

You're missing script called 'start' in Your package.json. Look at scripts/start line and add same (but modified for your file) in yours package.json

{
"private": true,
"scripts": {
    "dev": "npm run development",
    "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch-poll": "npm run watch -- --watch-poll",
    "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
    "prod": "npm run production",
    "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "start": "node index.js"
},
"devDependencies": {
    "axios": "^0.17.1",
    "babel-plugin-syntax-dynamic-import": "^6.18.0",
    "babel-plugin-transform-class-properties": "^6.24.1",

    "jquery": "^3.2",
    "laravel-mix": "^1.0",

    "react": "^16.5.1",
    "react-dom": "^16.4.0"
},
"dependencies": {
    "antd": "^3.12.4",
    "babel-plugin-import": "^1.8.0",
    "css-loader": "^2.1.0",
    "less": "^3.9.0",
    "less-loader": "^4.1.0",

    "redux": "^4.0.0",
    "redux-thunk": "^2.3.0",
    "style-loader": "^0.23.1"
}

}

I tried deleting, and reinstalling everything from the beginning in the future, to be, project folder and ran the latest react install and it worked for me.

try again: npm i -g create-react-app (without version number and in the folder where you plan to do work)

tips: don't over complicate debugging sometimes out of fear, and sometimes try different versions of software despite tutorial dictation.

• Good Luck!
