Question

I'm getting npm ERR! code ELIFECYCLE when I try to run my server command
What I'm trying to do is
TensorFlow.js Training in Node.js
It's for college, step 3 says to try out the server I get this
package.json snip
"scripts": {
"start-client": "webpack && webpack-dev-server",
"start-server": "node server.js"
},

run();
I already tried:
cache clean --force/-f, delete node_modules package-lock.json run npm install
removing package-lock.json and running the server
npm install -g node-pre-gyp
npm install --unsafe-perm
Changing the port from 8001 to 10000 3000 80
running it with every single thing else on my computer closed (this includes my xampp on the bg)
some info
node -v 14.15.1
npm -v 6.14.8
windows 10 x64
My grade needs me to overcome this and finish the tutorial
