NPM build script doesn't run

I'm trying to run babel as a build step in my project, but it doesn't seem to work.

My package.json looks like this:

{
  "name": "module-name",
  "version": "1.0.0",
  "description": "My Module",
  "main": "build/index.js",
  "scripts": {
    "test": "karma start",
    "build": "./node_modules/.bin/babel src -d build"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-cli": "^6.23.0",
    "babel-preset-env": "^1.1.8"
  }
}

And .babelrc, in the same directory, looks like this:

{
  "presets": ["env"]
}

The command npm test works fine and the Karma tests run. But when I use npm build --verbose, I just get the following output:

npm info it worked if it ends with ok
npm verb cli [ 'C:\\Program Files\\nodejs\\node.exe',
npm verb cli   'C:\\Users\\Peter\\AppData\\Roaming\\npm\\node_modules\\npm\\bin\\npm-cli.js',
npm verb cli   'build',
npm verb cli   '--verbose' ]
npm info using [email protected]
npm info using [email protected]
npm verb exit [ 0, true ]
npm info ok

But the Babel command did not run and the build directory is not created. However, running the command ./node_modules/.bin/babel src -d build directly from the command line works perfectly.

Any ideas what might be causing the problem?

npm test is a built in npm command, but your build command is not built in.

For npm commands that are not built in you need to run them:

npm run build
