node.js - 使用 genType 导出具有超过 1 个参数的 rescript 函数时出现 Curry.js 错误

问题描述

当导出具有超过 1 个参数（2 个或更多）的函数时，它会引发以下错误，这基本上表示我们 import 的方式存在问题curry.js。我在下面附上了一个示例和软件包版本。

错误：

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: path/to/node_modules/rescript/lib/es6/curry.js
require() of ES modules is not supported.
require() of /path/to/node_modules/rescript/lib/es6/curry.js from /path/to/src/demo.gen.ts is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename curry.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /path/to/node_modules/rescript/lib/es6/package.json.

例子

演示.res
@genType
let helloWord = (firstName: string, lastName: string): unit => {
  Js.log("Hello " ++ firstName ++ " " ++ lastName)
}
演示.bs.js
// Generated by ReScript, PLEASE EDIT WITH CARE
'use strict';


function helloWord(firstName, lastName) {
  console.log("Hello " + firstName + " " + lastName);
  
}

exports.helloWord = helloWord;
/* No side effect */
演示.gen.ts
/* TypeScript file generated from demo.res by genType. */
/* eslint-disable import/first */


// @ts-ignore: Implicit any on import
import * as Curry__Es6Import from 'rescript/lib/es6/curry.js';
const Curry: any = Curry__Es6Import;

// @ts-ignore: Implicit any on import
import * as demoBS__Es6Import from './demo.bs';
const demoBS: any = demoBS__Es6Import;

export const helloWord: (firstName:string, lastName:string) => void = function (Arg1: any, Arg2: any) {
  const result = Curry._2(demoBS.helloWord, Arg1, Arg2);
  return result
};
包.json
{
    "ts-node": "^10.2.1",
    "gentype": "^4.1.0",
    "rescript": "^9.1.4",
    "typescript": "^3.9.6"
}

节点版本

$ node -v
v15.11.0

操作系统

解决方案

在 genType 中查看此文件后：https ://github.com/rescript-association/genType/blob/fb6201266558a64d62441f7ac0d8d6652456397a/src/Config_.ml

我找到了这个选项

{
  "gentypeconfig": {
    "module": "commonjs",
  }
}

解决问题的设置 :D 不幸的是，我在 rescript docs 的其他任何地方都找不到它 :(
