真的在为此苦苦挣扎。我正在尝试在节点 14 (AWS Lamda) 上运行 ESM 脚本

我正在尝试运行此代码以将 3D 对象转换为三个 JSON。

这需要node -r esm fbx2three.js model.fbx运行。

我想我可以用我在这个博客中找到的这种方法来做到这一点

IE

索引.ts

import Convert from './runner.js'

Runner.js

require = require("esm")(module);
module.exports = require("./converter.mjs").default;

转换器.mjs

import { OBJLoader } from 'three/examples/jsm/loaders/OBJLoader.js'

export default function convertObj(url){
    const loader = new OBJLoader()
    const json = loader.parse(url).toJSON()
}

我现在在编译时遇到了这个错误

Object.defineProperty(exports, "__esModule", { value: true });

ReferenceError: exports is not defined

From converter.mjs:2:29

哪个编译为

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
const OBJLoader_js_1 = require("three/examples/jsm/loaders/OBJLoader.js");
function convertObj(url) {
    const loader = new OBJLoader_js_1.OBJLoader();
    const json = loader.parse(url).toJSON();
}
exports.default = convertObj;

tsconfig

{
  "compilerOptions": {
    "outDir": "./bin",   
    "rootDir": "./src", 
    "lib": ["esnext"],
    "target": "es6",

尝试使两者都为假（或删除），

  • esModuleInterop
  • 允许合成默认导入
