Getting npm start error while creating a react app

I've created a react app, but I am struggling with a problem which it is caused in npm start. The error pops up whenever I use the command react-scripts start on my windows 7 32 bit OS.

(NOTE: I used npx create-react-app my-react to creatr the app)

Here is the error :


> [email protected] start D:\WEB DEVELOPMENT\MyReact\my-react
> react-scripts start

internal/modules/cjs/loader.js:628
  throw e;
  ^

You can try this:

  1. Delete node_modules folder
  2. Delete the package-lock.json file which is at the root of your repository
  3. Run these commands: npm install and then npm start

Explanation: It looks like some packages were installed incorrectly. These instructions will uninstall the various packages your react app needs to run propertly, and install them again.
