Webpack 13 verbose stack Error: my-project#1.0.0 build: webpack --mode development - windows

Question

I'm attending a bootcamp running Mac and using windows at home. I downloaded a webpack project from github to run on my windows 7 system and it won't build. I found this error in a search and it advised running
npm install webpack-dev-server#2.9.7 --save-dev
, but the error persists. I tried starting over on my Win10 laptop and i get the same error.
I did find guidance that on package.json, I should change this line:
"start": "npm run build & webpack-dev-server --open --mode development",
The change was previously using a semi-colon instead of "&". Still no joy.
I need some help.
here is the error log:
