I am learning React and while implementing my first react app, it shows me this error:

error Command "start" not found.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

when I run:

yarn start

I have installed create-react-app globally on my machine.

I also tried to run npm start but it shows the same error, while searching on internet, I came to know that npm version 5.0 above may not work properly, and that is why I tried yarn start but it still shows the same error.

    @code_ghost To start a new React project, each time you have to do npx create-react-app my-app --use-yarn or "--use-npm". "do i always have to install react": What do you mean? "React" is a UI library, yes it will be automatically get installed locally in each project you start. Commented Jun 4, 2020 at 18:46
