k6.io引入util包TextDecoder读二进制文件报错及解决

我在使用k6.io做性能测试时，想要通过导入util包的TextDecoder来读取二进制文件，编写的测试脚本如下：

import { sleep, check } from 'k6';
import { Options } from 'k6/options';
import http from 'k6/http';
/* @ts-ignore */
import { TextDecoder } from 'util';


export const options:Options = {
  vus: 1,
  iterations: 1,
};

const file = open('uuids.txt', 'b');


export function setup() {

  console.log("File is " + file);

  let enc = new TextDecoder("utf-8")

  console.log("Decode: " + enc.decode(file));


}

export default () => {

}

我已经执行npm install util --save-dev安装了util依赖，对应的package.json配置如下：

{
  "name": "typescript",
  "version": "1.0.0",
  "main": "index.js",
  "repository": "ssh://git@github.com/k6io/example-typescript.git",

    "@babel/plugin-proposal-object-rest-spread": "7.13.8",
    "@babel/preset-env": "7.13.15",

  },
  "scripts": {
    "start": "webpack"
  },
  "browser": {
    "fs": false,
    "path": false,
    "os": false
  }
}

但执行k6 run dist\post-201-create-node-test.js命令时，出现util包未解析的错误，报错信息如下：

k6 run dist\post-201-create-node-test.js

最终我通过SharedArray读取JSON格式的测试数据解决了该问题，代码如下：

const data = new SharedArray('some data name', function () {
  return JSON.parse(open('./data.json')).uuids;
});
