subprocess.unref()

默认情况下，父进程将等待分离的子进程退出。要防止父进程等待给定的 subprocess 退出，请使用 subprocess.unref() 方法。这样做会导致父进程的事件循环不将子进程包含在其引用计数中，从而允许父进程独立于子进程退出，除非子进程和父进程之间建立了 IPC 通道。

¥By default, the parent process will wait for the detached child process to exit. To prevent the parent process from waiting for a given subprocess to exit, use the subprocess.unref() method. Doing so will cause the parent's event loop to not include the child process in its reference count, allowing the parent to exit independently of the child, unless there is an established IPC channel between the child and the parent processes.

const { spawn } = require('node:child_process');
const process = require('node:process');

const subprocess = spawn(process.argv[0], ['child_program.js'], {
  detached: true,
  stdio: 'ignore',
});

subprocess.unref();import { spawn } from 'node:child_process';
import process from 'node:process';

const subprocess = spawn(process.argv[0], ['child_program.js'], {
  detached: true,
  stdio: 'ignore',
});

subprocess.unref();拷贝
