mkdir -p doesn't work in package.json script on Windows

Say, we have a React app, and there's a script in package.json:

"scripts": {
    "create-images-dir": "mkdir -p distrib/images"
}

If to run this script via npm run create-images-dir on Linux, it works fine. But trying to run it on Windows environment in git-bash or Cygwin terminal, I'm getting this error:

The syntax of the command is incorrect.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! Exit status 1

Same error with setting --parents instead of -p. Without -p parameter, it works, so it stumbles on -p. But at the same time, the command from script works fine if typed manually in terminal:

mkdir -p distrib/images

For me, it looks like some symbol escaping occurs when command is translated from script to execution, or different processing of nested directories on Windows, but I have no idea what exactly it is. Am I doing something wrong?

On Linux the correct syntax to create directory recursively is:

mkdir -p distrib/images

On Windows you don't have to specify -p.

You can use mkdirp package as suggested by @dmfay or use os in your package.json to not include -p when on windows.

This is why the mkdirp package exists -- add it as a dev dependency and use the binary mkdirp in your script instead of the platform-specific mkdir.
