node.js - 将标志 `--experimental-worker` 与 babel-node 一起使用

Question

babel-node --experimental-worker app.js

使用此命令以开发模式启动我的项目。输出是:

error: unknown option--experimental-worker'

配置.babelrc:

{ "presets": [ ["env", { "targets": { "node": "current" } }], "stage-0", "flow" ], "plugins": [ "transform-decorators-legacy", "transform-flow-strip-types" ] }

使用工作线程需要此标志。使用 babel 6.26

我今天刚遇到这个问题并在 GitHub 上回复了这个问题 here .我在下面粘贴了我的修复:

I was using Nodemon, and it turns out that there's an option to include environment variables as NODE_OPTIONS in the nodemon.json file. This did the trick for me:

{
  "watch": ["server"],
  "ext": "js",
  "env": {
    "NODE_OPTIONS": "--experimental-worker"
  },
  "exec": "babel-node server/server.js"
}

How to integrate Nodemon + worker_threads into a normal NodeJS app:

1. Set up Nodemon
2. Add a nodemon.json file to the root folder (example here)

3. Add this to nodemon.json:

   "env": { "NODE_OPTIONS": "--experimental-worker" }

If you're setting up Nodemon for the first time, I found this tutorial very helpful.
