ts-node 执行带有模块导入和模块定义的打字稿 [英] ts-node execute typescript with module import and module defined

问题描述

我尝试通过打字稿初始化数据库库.

I try to initialize database base via typescript.

我的 ts 就像:

import { User, UserRole } from '../entity/User';
import crypto from 'crypto';
import {dbManager, pwhash } from '..';

async function inituser() 
{
    const user = new User();
    user.email = '[e-mail]';
    user.own_organization = []
    user.salt = crypto.randomBytes(16).toString('hex');
    user.password = pwhash("password", user.salt);
    user.role = UserRole.admin;
    await dbManager.save(user);
    const duser = await dbManager.findOne(User);
    return duser;
}
const duser = inituser();

console.log("Loaded users: ", duser);

当我尝试通过 ts-node 运行脚本时:

when I try to run the script by ts-node like:

npx ts-node db/initializers/inituser.ts

有错误:

我添加了类型":模块"；在 package.json 文件中.

I add "type": "module" in package.json file.

{
  "name": "typescript-test",
  "version": "1.0.0",
  "type": "module",
...
}

为了克服

(node:3854) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)

推荐答案

错误 Warning: To load an ES module, set "type": "module";在 package.json 或 中是由 ts-node 中的以下错误引起的:https://github.com/TypeStrong/ts-node/issues/935

The Error Warning: To load an ES module, set "type": "module" in the package.json or is caused by the following Bug in ts-node: https://github.com/TypeStrong/ts-node/issues/935

Bug 关闭了，有解决的提议，但是还是打开了:https://github.com/TypeStrong/ts-node/issues/1007

The Bug is closed, and there is a proposal to solve it, but it is still open: https://github.com/TypeStrong/ts-node/issues/1007

我不需要 "type": "module" 在 package.json 中，我正在使用 "module": "commonjs" 而不是 "module": "es6", 在 tsconfig.json 中.我注意到这是因为 ts-node 问题 #1007 已解决的技术债务.

I don't need "type": "module" in package.json and am using "module": "commonjs" instead of "module": "es6", in tsconfig.json. I noted this as technical debt pending that ts-node issue #1007 is resolved.
