My dog deleted all environment variables PATH's in Win 10, now "npm start" doesn't work

Question

Everything was working perfectly fine with "npx create-react-app" and "npm start", until I didn't install Python and my dog delete all env. vars. PATH's in win 10,

and set:

C:Python38-32Scripts
C:Python38-32
C:Python38-32airline

later I added:

C:Program Files
odejs

so now "npx create-react-app" is working, but not and "npm start"

I google to find win 10 defaults and added:

C:Windowssystem32
C:Windows
C:WindowsSystem32Wbem

now I have:

C:Python38-32Scripts
C:Python38-32
C:Python38-32airline
C:Program Files
odejs
C:Windowssystem32
C:Windows
C:WindowsSystem32Wbem

How to fix that?

Thank's

Answer 1

So I install fresh windows 10, update windows, installed node.js, and VS code.

THIS IS THE ENV. VAR. PATH'S - NOW EVERYTHING IS WORKING!!!
