Error missing script build

Question

How can I fix this error, I am running Windows 10

When I try to run npm run build on cmd, I get this error

C:\Users\anai_> npm run build
npm ERR! missing script: build

Here is the startup log

11 error missing script: build
12 verbose exit [ 1, true ]

Although the error refers to a missing build script , I put the 'build' script in my package.json package

{
  "name": "es6",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "build": "webpack"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "webpack": "^3.8.1"
  }

}

and this is my webpack.config.js file

module.exports = {
  entry: ['./app/index.js'],
  output: {
    path: './build',
    filename: 'bundle.js'

  }
}

Can someone tell me how to fix this error or where it comes from. I am new to using node.js, webpack and command line. Thank you in advance for your time!

It may also be useful to delete an empty src user folder (or where you usually store it package-lock.json, etc.). This may appear, for example, when you extract and switch between different branches, and some branches have already deleted the ui src folder, but git does not delete empty folders.
