Heroku 在导入“aws-sdk”时崩溃

【中文标题】Heroku 在导入“aws-sdk”时崩溃【英文标题】：Heroku crashes when importing 'aws-sdk' 【发布时间】：2020-10-18 00:53:30 【问题描述】：

我有 typescript node.js 应用程序，我在其中使用 Amazon S3。它已部署到 Heroku。

import express from 'express';
import cors from 'cors';
//import aws from 'aws-sdk';
import dotenv from 'dotenv';
dotenv.config();

const app = express();
app.use(express.json());
app.use(cors());

const PORT = process.env.PORT || 3001;

app.get('/ping', (request, response) => 
  console.log('ping');
  response.send('pong');
);

app.listen(PORT, () => 
  console.log(`Server running on port $PORT`);
);

问题是如果我取消注释 import aws from 'aws-sdk' Heroku 会崩溃并出现以下错误：

当我在本地运行相同的项目时，它运行良好。当我将“aws-sdk”与常规 JavaScript 应用程序一起使用时，不会发生此错误。我不明白为什么 Heroku 在导入“aws-sdk”时会崩溃？

以下是我的“package.json”：
