vscode 调试器意外令牌“导入”

Question

我是 nodejs 和 vscode 的新手……我有两个文件：entry.js 和 /utils/database.js。

当我运行 node entry.js 时，我得到了我期望的小日志记录 (SSSS)。我想在调试模式下运行它，以便我可以构建它，但是当我点击左侧调试中的“运行”时，我得到：

SyntaxError: Unexpected token import

utils/database.js：

import mysql from "mysql";

export const pool = mysql.createPool({
  connectionLimit: 100,
  host: "localhost",
  user: "root",
  password: "password",
  database: "no_replicate",
});

entry.js：

"use strict";

import { pool } from "./utils/database.js";

pool.end(function (err) {
  if (err) {
    return console.log("error:" + err.message);
  }
  console.log("Close the database connection.");
});

pool.getConnection(function (err, connection) {
  // execute query
  // ...
  console.log("SSSS");
});

任何帮助都会让我开心。谢谢

在 utils/database.js 中：

const mysql = require("mysql");

const pool = mysql.createPool({
  connectionLimit: 100,
  host: "localhost",
  user: "root",
  password: "password",
  database: "no_replicate",
});
module.exports = pool

在 entry.js 中

const pool = require('./utils/database.js');

pool.end(function (err) {
  if (err) {
    return console.log("error:" + err.message);
  }
  console.log("Close the database connection.");
});

pool.getConnection(function (err, connection) {
  // execute query
  // ...
  console.log("SSSS");
});

在 Nodejs 中，我们像 require('package-name') 一样导入
