Failed to exec start script

Angular: 5.0.1 / Angular CLI: 1.5.0 / Node: 8.9.1 / npm: 5.5.1 / Os: win32 x64

I get the below error when executing "npm start" in the terminal/command prompt. Can anyone help me resolve this? I have spent a whole day trying to fix it with no luck.

Here is the scripts section of my package.json

"scripts": {
    "start": "webpack-dev-server --inline --progress --port 8080"
  },

Here is the error
