ts-jest says `The requested module 'yargs/helpers' does not provide an export named 'hideBin'`

Hi, I have a question.

I’m going to use yargs in the project have ts-jest.

ts-jest said The requested module 'yargs/helpers' does not provide an export named 'hideBin' but I know yargs/helper have export function hideBin

This script that imported in main.spec.ts invoked this error.

setup.ts

import yargs from "yargs";
import { hideBin } from "yargs/helpers";
import path from "path";
import dotenv from "dotenv";
const __dirname = path.dirname(new URL(import.meta.url).pathname);

dotenv.config({ path: path.resolve(__dirname, "../.env") });
const args = yargs(hideBin(process.argv)).parse();

export default args;

I solved this problem not importing hideBin.

setup.ts (resolved problem)

import yargs from "yargs";
import path from "path";
import dotenv from "dotenv";
const __dirname = path.dirname(new URL(import.meta.url).pathname);

dotenv.config({ path: path.resolve(__dirname, "../.env") });
const args = yargs(process.argv.slice(2)).parse();

export default args;

It’s mysterious. Someone knows why this problem happen?

I’m using this jest.config.js

module.exports = {
  // [...]
  preset: "ts-jest/presets/default-esm", // or other ESM presets
  globals: {
    "ts-jest": {
      useESM: true,
    },
  },
  moduleNameMapper: {
    "^(\\.{1,2}/.*)\\.js$": "$1",
  },
};

@AndyClausen I believe the ESM version of yargs drops the magic .argv accessor, try the following:

import yargs from 'yargs'
import { hideBin } from 'yargs/helpers'

yargs(hideBin(process.argv))
  .command('curl <url>', 'fetch the contents of the URL', () => {}, (argv) => {
    console.info(argv)
  })
  .demandCommand(1)
  .parse()

.parse() is equivalent to .argv but less magic.

@praveendvd could you open an issue on ts-jest as well, perhaps they have some direction? This seems like a bug with how they’re handling ESM vs., CJS requires.

Already did it thank you
