Hi , I don't know if this problem is caused by tsup or @babel/parser ?

// index.ts

import parser from '@babel/parser'

const ast = parser.parse('let age = 1')
console.log(ast)

// index.js

var __create = Object.create;
var __defProp = Object.defineProperty;
var __getOwnPropDesc = Object.getOwnPropertyDescriptor;
var __getOwnPropNames = Object.getOwnPropertyNames;
var __getProtoOf = Object.getPrototypeOf;
var __hasOwnProp = Object.prototype.hasOwnProperty;
var __copyProps = (to, from, except, desc) => {
  if (from && typeof from === "object" || typeof from === "function") {
    for (let key of __getOwnPropNames(from))
      if (!__hasOwnProp.call(to, key) && key !== except)
        __defProp(to, key, { get: () => from[key], enumerable: !(desc = __getOwnPropDesc(from, key)) || desc.enumerable });
  }
  return to;
};
var __toESM = (mod, isNodeMode, target) => (target = mod != null ? __create(__getProtoOf(mod)) : {}, __copyProps(isNodeMode || !mod || !mod.__esModule ? __defProp(target, "default", { value: mod, enumerable: true }) : target, mod));

// src/index.ts
var import_parser = __toESM(require("@babel/parser"));
var ast = import_parser.default.parse("let age = 1");
console.log(ast);

// tsup.confug.js

import { defineConfig } from 'tsup'

export default defineConfig({
    entry: ['./src/index.ts'],
    splitting: false,
    sourcemap: false,
    clean: true,
    dts: false
})

then i run node index.js , the following error was reported:
