child_process normalizeSpawnArguments doesn't handle spaced arguments

[homobel]

v13.5.0
Windows 10 64

Reproduce:
npx gulp "full dev" =>
(normalizeSpawnArguments, args = ['full dev'] ) const command = [file].concat(args).join(' '); =>
"path/to/gulp.cmd full dev"

Can you provide a clearer statement of how to reproduce? Is there a Gulpfile or something that one needs to reproduce this problem?

[homobel]

Sorry, wanted to show real world example. Here is the minimal one: child_process.zip
Try 'node b'. It will log:

0) Hello
1) world

whereas I would expect rather
0) Hello world

Thanks!

For people who don't want to download anything (or in case the link becomes stale at some point):

a.js:

const args = process.argv.slice(2);


args.forEach((arg, i) => console.log(`${i}) ${arg}`));

b.js:

const { spawn } = require('child_process');

const a = spawn('node', [__dirname + '/a.js', 'Hello world'], {shell: true});

a.stdout.on('data', data => {
	console.log(data.toString());
});
