Typescript使用多线程worker_threads,import报错解决办法

报错如下,大概的意思就是import不支持,换句话说就是不支持ts语法

[root@VM-20-7-opencloudos xzserver]# nodemon server.ts

[nodemon] to restart at any time, enter `rs`

Worker 退出，退出码 1

原因大概就是子线程文件没有继承主线程文件的配置tsconfig.ts导致的问题

解决的办法也相对比较简单,但是要在调用子线程文件的主线程那边处理

子线程要这样子启动,保证你的模块里面包含tsnode,没有的话要下载

const worker = new Worker(path.resolve(__dirname, './worker.ts'),
    {execArgv: ['-r', 'ts-node/register', '--inspect']}); // 假设你的 Worker 文件名是 worker.ts

tsconfig.json如下

{
  "compilerOptions": {
    "esModuleInterop": true,
    // "module": "commonjs",
    "module": "CommonJS",
    "target": "ES6",
    "strict": true
  }
}
