不能在模块外使用 import 语句（nodeJs）

Question

我无法运行文件服务器。 JS。我已经尝试在 package.Json 中添加 “type”: module 并没有奏效。第一个代码是 server.js，第二个是 package.json。我也认为我不能使用 import 和 require？我不确定。

const express = require('express');
const app = express();
import { getUserList } from './user';

const userList =  getUserList();

app.get('/users', (req, res, next) => {
    return res.status(200).send({
        success: 'true',
        message: 'users',
        users: userList
    });
   
});

app.listen(8000, () => {
    console.log('Example app listening on port 8000!');
});
