Javascript 在docker内部运行时未找到节点导入模块

我有一个带有节点js服务器的小型react应用程序，具有以下导入：

import express from 'express'
import compression from 'compression'
import cookieParser from 'cookie-parser'
import bodyParser from 'body-parser'
import * as path from 'path'
import * as _ from 'lodash'
import { CloudConfigOptions, Config, ConfigObject } from 'spring-cloud-config'

import { ApiService } from './src/service/ApiService'
import { BackendEnum } from './src/service/BackendEnum'

然后是几个端点，例如：

server.put('/data', keycloak.protect('user'), (req: any, res: any) => { 
    ApiService.runSomeLogic();

    return res
})

在本地计算机上运行时：

npm run dev:express

服务器启动正常

现在的问题是，当我构建docker映像并尝试运行它时，会出现以下错误：

$ docker run my-container:1.0

> my-app@0.1.0 start /app
> cross-env NODE_ENV=production node server.js

internal/modules/cjs/loader.js:985

我很确定问题在于

ApiService

和

BackendEnum

的导入是如何定义的，但我缺乏节点/javascript知识，因此无法确定如何修复此导入

---

有人能发现我的导入有什么问题吗？为什么应用程序在docker容器中运行时会崩溃？

您不是在第二个容器中复制所有源代码，而是只复制一个文件，即server.js。冒犯的路线是

COPY --from=web-builder /src/server.js ./

把这行改成

COPY --from=web-builder /src ./

---

如果仍然报告错误，请提供错误日志。如果它有效，您就不需要另外两个复制语句。

我没有使用巴贝尔。我正在使用一个带有小型nodejs服务器的react应用程序。我编辑了这个问题以反映这个细节。很抱歉给你带来了困惑。我编辑了这个问题，将刚刚添加到
