Below are the errors i am getting.

C:\my-react-app>npm start

> [email protected] start C:\my-react-app

Starting the development server...

I faced the same issue and after banging my head for a while I figured out the problem. It is a very easy fix.

You just need to change the version of your react-scripts to 2.1.8 in your project's package.json file.

If you don't understand then Follow these baby steps :P .

1 Open the file package.json

This file is just inside your project folder. If you are using an editor like VSCode then you can use it to see this file.

2 Change react-scripts version

Inside package.json you will see dependencies block.

  "dependencies": {
    "react": "^16.8.6",
    "react-dom": "^16.8.6",
    "react-scripts": "3.0.0"
  },

Right now we have the latest version which is 3.0.0. And I guess this is the real culprit here.

Change it to 2.1.8. See the image snap of my project.

3 Run npm install again and try npm start

Now it will work. I don't know why the version 3.0.0 is causing issue. But at this moment I think there is some bug, or may be anything else that I don't know yet.

May be the issue is something else, and something more specific. But so far I figured out this only.

Hope this helps you. Thank You :)
