npm package development run executable

问题

I'm creating a module (foo) with an executable. I've used npm link to make sure the package can be tested locally. This module has a dependency (bar) with an executable. I want to access this executable inside my executable.

mainProject
|
|- foo
   |
   |- bar




// cli.js (foo/cli.js)
import { spawnSync } from 'child_process';

async function main(argv: string[]) {
    const version = require('../package.json').version;

    commander
        .command('test')
        .action(async () => {
            const { stdout, stderr, error } = spawnSync('bar --help');
        });

    commander.parse(argv);
}

export default main;

If I call foo test from my main project it fails I get:

Error: spawnSync bar --help ENOENT
