--allow-worker

在使用 权限模型 时，默认情况下该进程无法创建任何工作线程。出于安全原因，除非用户在主 Node.js 进程中显式传递 --allow-worker 标志，否则调用会抛出 ERR_ACCESS_DENIED。

【When using the Permission Model, the process will not be able to create any worker threads by default. For security reasons, the call will throw an ERR_ACCESS_DENIED unless the user explicitly pass the flag --allow-worker in the main Node.js process.】

示例：

【Example:】

const { Worker } = require('node:worker_threads');
// Attempt to bypass the permission
new Worker(__filename); 拷贝

$ node --permission --allow-fs-read=* index.js
