Repository: create-react-app
Issue: NPM Start issue
Labels: needs triage

Hi,
I have installed node to learn react. When I create a react app using `npx create-react-app`, all the files are downloaded. But when I trying running `npm start`, it doesn't do anything. I have tried re-installing node and vs code but nothing see,s to work.
The file I'm working on is called github-finder.
Npm version: 6.14.8, Node Version: v14.15.1
I was able to run npm scripts. I made a new directory and ran npm init. These were the contents of the package.json
```
{
  "name": "test",
  "version": "1.0.0",
  "description": "testing",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}
```
The contents of the GitHub-finder directory.

Tried running `npm run start`. Nothing changed, just moves to a new line.
I'm working on windows 10.
Any idea why this is not working?
