VSCode调试Typescript应用程序

我有一个用TypeScript编写的应用程序，它使用 import 语句 . 我按照指令here在VSCode中启用调试 . VSCode构建命令在out-tsc中创建输出.js和.map文件 . 但是，当我尝试调试时，我收到以下错误：

Debugger attached.

}

值得注意的是，从js中删除了该类型的导入，并且导致失败的函数被导入 .

app.ts

import { HandlerDef } from '../../shared/handler/handler-def';
import { initQueues } from '../../shared/firebase-app';

const handlers: HandlerDef[] = [
];
initQueues('app', handlers);

app.js（由VSCode编译）

import { initQueues } from '../../shared/firebase-app';
const handlers = [];
initQueues('app', handlers);
//# sourceMappingURL=/Users/integrityinspired/Documents/Dev/basilisk-island/server/src/app.js.map

火力点，app.ts

import * as firebase from 'firebase';
import * as Queue from 'firebase-queue';
import { HandlerDef } from './handler/handler-def';
import { createQueue } from './queue-wrapper';

export function initQueues(queue: string, handlers: HandlerDef[]): void {
    const config = firebaseConfig();
    firebase.initializeApp(config);
    let envSuffix: string = '';
    if (process.env.NODE_ENV === 'development') {
        console.log('Running in dev mode');
        envSuffix = '-dev';
    }
    const ref = firebase.database().ref(`/queue${envSuffix}/${queue}`);
    handlers.forEach(def => {
        createQueue(ref, def);
    });
}
