请问,为何不能这样运行ts文件呢?

文件util.ts

import ip from 'ip'

export const getLocalIPs = () => {
  //var ip = require("ip");
  console.dir ( ip.address() );

  return ip.address()
}

文件:__test__/util.test.ts

export default {} 

import { getLocalIPs } from '../util'

getLocalIPs()

然后我在执行:

npx ts-node __test__/util.test.ts 

的时候,报错:

npx ts-node  util.test.ts 
(node:61127) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)

import { getLocalIPs } from '../util';

请问,这个报错的原因是什么呢? 我已经在

文件:__test__/util.test.ts
添加了导出啊:

export default {} 

编辑1:我已经添加package.json
  "type": "module",

但是现在报错找不到util模块:

CustomError: Cannot find module '/Users/john/Desktop/projects/个人/nextjs/renderer/components/func/Traceroute/util' imported from /Users/john/Desktop/projects/个人/nextjs/renderer/components/func/Traceroute/__test__/util.test.ts

请问这种情况还有什么问题呢?

package.json里设置"type": "module":

"type": "module"

或者tsconfig.json配置:

{
  "compilerOptions": {
    "module": "ESNext"
  }
}

ts-node 好久没维护了,配合现代 JS 麻烦一大堆,不如用 tsx 这个 cli
