What steps will reproduce the bug?

1. Write the following to test.js and make it executable:

   #!/usr/bin/env node
   console.log('hello');
   

2. NODE_OPTIONS="--watch" ./test.js

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

This is always reproducible.

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

I would expect it to run normally, producing hello in stdout and then exiting.

What do you see instead?

There is no output. I can see in my process list that there are hundreds of node processes spawning.

Additional information

This seems to be the same issue as https://github.com/nodejs/node/issues/51159. For additional context, my intent was to reuse a bin entrypoint in package.json but with --watch mode, so under the scripts field it looked roughly like:

"scripts": {
    "dev": "NODE_OPTIONS='--watch' app",
}

...where app is in node_modules/.bin/.

首先使用 NODE_OPTIONS="--watch" 重现可执行入口点命令，并将其与 issue #51159 进行比较。跟踪可执行文件和 package bin 入口点的 watch 模式处理，然后添加或更新回归测试；完成的标准是该命令打印一次 hello 后退出，且不生成进程。
