How to run npm scripts from global packages?

Say, I am making a npm package.

sample package.json:

{
   "bin": { "cli": "cli.js" },
   "scripts": { 
    "sample": "node sample.js" 
   } 
}

sample cli.js:

const shell = require('shelljs')
shell.exec('npm run sample')

Then, I run npm link

Now, if I run cli from anywhere, other than the project repository, it does not run. Instead, it throws an error.

I found a workaround by changing cli.js as:

const shell = require('shelljs')
, package_path = require('./path.json') 
// I manually created this path.json containing the absolute path of the package

shell.exec('npm run --prefix ${package_path} sample')

This sort of works. But main limitations are:

• all contributors of the project must manually set this path after cloning the repo.

• if the package is globally installed like npm i -g package then this path changing is annoying for the user.

What I'm asking is:

• How can I automate setting the path?

• Any other better way to achieve the same behavior, that is, calling a npm script from a global cli script?
