考虑以下文件：

import { second } from "./second";

$(() => {

    second.Test();
});

//import * as $ from "jquery";
//import * as _ from "lodash";

export const second = {
    Test: () => {
        const message = _.identity("second.ts");
        $(".second").html(message);
    }

const path = require('path');

是否有一种方法可以在所有.ts文件中强制执行导入语句？
考虑在网页包配置中使用externals选项：

我想它的用途与您的用例非常匹配。
很有趣，谢谢您的回答。这看起来像是支持与我的用例相反的东西；当“import”语句丢失时，我试图引发一个错误-我不知道如何使用externals
选项来实现这一点。
