專案使用typescript並用webpack打包

本地端直接使用nodemon可以正確執行
使用webpack打包後可以使用node index.min.js執行
但是打包成docker image後卻無法正確運行container

node:internal/modules/cjs/loader:944
  throw err;
  ^

Error: Cannot find module 'dotenv/config'

• webpack設定檔

const path = require('path');
const webpack = require('webpack');
const nodeExternals = require('webpack-node-externals');

module.exports = {
  target: 'node',
  mode: 'production',
  entry: './src/server.ts',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'index.min.js',
  },
  optimization: {
    // minimize: false,
  },
  resolve: {
    // Add `.ts` and `.tsx` as a resolvable extension.
    extensions: ['.ts', '.tsx', '.js'],
  },
  externals: [nodeExternals(), 'pg', 'sqlite3', 'tedious', 'pg-hstore', 'dotenv/config'],
  plugins: [
    new webpack.ContextReplacementPlugin(/Sequelize(\\|\/)/, path.resolve(__dirname, './src')),
  ],
  module: {
    rules: [
      // all files with a `.ts` or `.tsx` extension will be handled by `ts-loader`
      { test: /\.tsx?$/, loader: 'ts-loader' },
    ],
  },
};

• dockefile

FROM node:current-alpine3.12
RUN mkdir /src
COPY dist /src
COPY .env /src
WORKDIR /src
CMD ["node","index.min.js"]

• tsconfig

{
  "compilerOptions": {
    "strict": true,
    "esModuleInterop": true,
    "outDir": "build"
  }
}

原本以為是dotenv/config的問題

改用

require('dotenv/confit).require()

之後卻又變成找不到express

有前輩遇過類似的問題嗎？
