Urgent Help; Unable to run a project on local system

So I cloned Clement Mihailescu’s Pathfinding Visualizer Tutorial into my system and have upgraded nvm to v16.2.0 and npm to 7.15.1.

According to the ReadMe file, here are the steps that I am supposed to follow:

In the project directory, you can run:

npm start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

But when I run npm start, this is what I get:

Can somebody please help me here?
It would be really helpful of you. Thanks!

You have to install the dependencies first, I guess.
Try running npm install and then after it, run npm start

Maybe you’d rather just play with the sandbox?

Otherwise, try the first answer from here.
