I assume you already ran npm install ?

[RaisinTen]

Yes, that ran perfectly. :)

npm run <command>

will run bash script from package.json from 'scripts' value of '' attribute. For example:

package.json

   "name": "app",
   "version": "0.0.0",
   "license": "MIT",
   "scripts": {
      "server": "webpack-dashboard -- webpack-dev-server --inline --port 8080",
      "webdriver-update": "webdriver-manager update",
   },
  "dependencies": {
   "@angular/common": "~2.2.0",
   "@angular/core": "~2.2.0"
   },
  "devDependencies": {
   "@types/core-js": "^0.9.0"
   }
}

In this case you can run scripts:

npm run server
npm run webdriver-update

In your case you probably wont have dev script.

Remember that few scripts name are reserved (for example npm test will try to run, npm run pretest, npm run test, npm run posttest). More info on https://docs.npmjs.com/misc/scripts

Simply check the package.json file and see what the name of the key is for dev. In my case it was start instead of dev, so I ran npm run start and that did it.

@An-prog-hub actually, the dev script exists already:

node-addon-api/package.json

Line 302 in 8fb5820

"dev": "node test",
