`process.execArgv` does not include `--watch` or `--watch-path` options or their values on Windows

Version

v24.11.0

Platform

Microsoft Windows NT 10.0.19045.0 x64

Subsystem

process

What steps will reproduce the bug?

1. Create a build.js file:

/** @file build.js */
import { execArgv } from "node:process";
console.warn(execArgv);

2. Create an empty file named template.html (content does not matter).

3. Run the following command:

(node --watch-path=template.html build.js & node --watch-path template.html build.js & node --watch build.js) > /dev/null

How often does it reproduce? Is there a required condition?

Always reproducible when --watch or --watch-path options are specified on the node command line.

What is the expected behavior? Why is that the expected behavior?

Expected output:

[ '--watch-path=template.html' ]
[ '--watch-path', 'template.html' ]
[ '--watch' ]

According to Node.js documentation, process.execArgv should contain the Node options passed before the script name.

What do you see instead?

Additional information

Bash is installed on my Windows system. I used it in the reproduction steps because it makes it easier to chain blocking commands and run them in the background compared to PowerShell or Command Prompt.
Press Ctrl+C to terminate all background processes at once.

Commencez par exécuter la commande de reproduction Windows et examinez comment process.execArgv gère les options --watch et --watch-path avant le nom du script. Le correctif est terminé lorsque les deux formes d’option et leurs valeurs apparaissent dans process.execArgv comme indiqué dans la sortie attendue, tout en préservant le comportement des trois commandes fournies.
