javascript - Node : bad option: --experimental-worker

Question

我正在尝试在 node.js 中使用 worker_threads。

const { Worker, isMainThread, parentPort } = require('worker_threads');
if (isMainThread) {
    // This code is executed in the main thread and not in the worker.

    // Create the worker.
    const worker = new Worker(__filename);
    // Listen for messages from the worker and print them.
    worker.on('message', (msg) => { console.log(msg); });
} else {
    // This code is executed in the worker and not in the main thread.

    // Send a message to the main thread.
    parentPort.postMessage('Hello world!');
}

我将以上代码保存在 index.js 中，并在终端上运行 node --experimental-worker index.js。 我收到以下错误:

node: bad option: --experimental-worker.

我在我的 mac 中安装了 Node 的 v8.16.0。

Answer 1

Worker nodejs v10.5.0 中添加了类。

要使用 --experimental-worker 至少需要 nodejs v10.5.0

与 nodejs v12.x稳定，无需--experimental-worker

即可使用

下载:nodejs

版本管理器:nvm
