Ran npm run start in Mac terminal got an ERR message

Hope someone can help with this. I was trying to run my protractor from my terminal for the 1st time and I got this error message.

The command I used was

npm run start

I had a look at my package.json script and that seems fine. Did I miss something?

note: 'xx' is nothing more than removing my name for confidentiality

npm.json file

{
  "name": "LocatorTraining",

  "dependencies": {

  "protractor":  "^5.4.1"

  },


  "scripts": {
    "webdriver-update": "./node_modules/.bin/webdriver-manager update",
    "webdriver-start": "./node_modules/.bin/webdriver-manager start",
    "protractor": "./node_modules/.bin/protractor configurations.js",
    "start": "npm run webdriver-manager update &&npm run webdriver-manager start"
  }

}

Message from terminal
