@Yonben Right, thanks

In your console run PORT=3001 yarn start

[diptiborade]

change port in console before running
SET PORT=3100

then run the command
npm start

On my pc:

E:\ReactJs\reactapp2>SET PORT=3100

E:\ReactJs\reactapp2>npm start

[email protected] start E:\ReactJs\reactapp2
react-scripts start

Compiled successfully!

I documented the various options one can choose in order to change the default port. You can set the environment variable as shown in the comment above, change the start command, or create .env file. Here is the full article.

Windows users change the script like this:
"scripts": { "start": "set PORT=5000 && react-scripts start",

and Linux and Mac users like this:
"scripts": { "start": "PORT=5000 react-scripts start",
