operable program or batch file.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! @ development: `mix`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the @ development script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

mix command not found - what is mix when i runned dev?

'mix' is not recognized as an internal or external command, operable program or batch file.

You have declared a dev command in your package.json file, which, when invoked as npm run dev, runs the associated commands. In this case, the code might be:

{
  "scripts": {
    "dev": "npm run development",
    "development": "mix",
  }
}

1. call dev with npm run dev (you runned it)
2. call development by dev (automated by associated command)
3. call mix by development (automated by associated command)
4. Get error: mix not found (error message on your console)

How to can add mix command to project?

So, running npm run dev actually starts the same thing as if you entered mix in the console. However, the mix command does not exist. This is because you have not installed the laravel-mix package.

npm install laravel-mix@latest --save-dev

IMPORTANT: Remember that just because the dependency name is listed in the package.json file doesn't mean that you have actually installed it! You can easily check this by running the npm install command!
