Why is next js not running?

Question

Node.js

I do everything according to the instructions https://nextjs.org/learn/basics/getting-started/setup
I start npm run dev
And display an error

[email protected] MINGW64 /f/nextjs/hello-next
$ npm run dev

> [email protected] dev F:\nextjs\hello-next
> next

> Couldn't find a `pages` directory. Please create one under the project root
