Answer 1

It means you're missing a script.NPM should know which script to run when that command is executed. If you have a build script, in your package.json, under scripts:

"scripts": {
    "test": "jest"
    "build": "name of your build script"
  },  

For example, on one of my projects,

"scripts": {
    "lint": "./node_modules/.bin/eslint .",
    "lint:fix": "./node_modules/.bin/eslint . --fix || true",
    "build": "babel src -d dist --presets es2015",
     .....
  }

Your node version: 4.2.6 Node version required by latest version of webpack : minimum 6.11.6 You either need to update your node or use a version of webpack that's compatible with our node version
