我正在尝试使用webpack构建一个小项目node.js + ts。

tsconfig.json
{
  "compilerOptions": {
    "lib": ["ESNext"],
    "target": "ES2020",
    "module": "NodeNext",
    "moduleResolution": "NodeNext",
    "esModuleInterop": true,
    "types": ["node"],
    "allowSyntheticDefaultImports": true,
    "rootDir": "./"
  },
}

我将其添加到package.json行"type": "module"

webpack.config.ts
import * as path         from 'path';
import * as webpack      from 'webpack';
import { fileURLToPath } from 'url';

const __dirname = path.dirname(fileURLToPath(import.meta.url));

const PATHS = {
  entry:  path.resolve(__dirname, 'src/server/index.ts'),
  output: path.resolve(__dirname, 'dist'),
};

const config: webpack.Configuration = {
  target:  'node',
  entry:   PATHS.entry,
  output:  {
    path:     PATHS.output,
    filename: 'bundle.js',
  },
  module:  {
    rules: [
      {
        test:    /\.ts(x?)$/,
        use:     'ts-loader',
        exclude: '/node_modules/',
      },
    ],
  },
  resolve: {
    extensions: ['*', '.js', '.jsx', '.json', '.ts', '.tsx'],
  },
};

export default config;

通过运行命令"build": "webpack --config config/webpack.config.ts --mode development"，我得到一个错误：
[webpack-cli]无法加载"/node_esm/webpack. config. ts "配置[webpack-cli]类型错误[ERR_UNKNOWN_FILE_EXTENSION]：/node_esm/webpack. config. ts的文件扩展名". ts"未知
我试着添加到我的config.json"ts-node": { "esm": true}中，但没有帮助解决我的问题。我需要做什么才能用webpack构建一个应用程序？

• 节点：v16.18.1
• ts加载程序：v9.4.2
• typescript ：v4.9.4
• 网络包：v5.75.0
• 网络包-客户端：5.0.1
• • UPD**我尝试过更改tsconfig。第一个选项是打开tsconfig.json文件并查找compilerOptions。将target设置为"ES5"，将module设置为"CommonJS"（或者完全删除module选项）。

{
  "compilerOptions": {
    "target": "ES5",
    "module": "CommonJS",
    "moduleResolution": "NodeNext",
    "esModuleInterop": true,
    "types": ["node"],
    "allowSyntheticDefaultImports": true,
    "rootDir": "./"
  }
}

错误仍然存在。第二个选项是添加ts节点的设置：
您可以保留"模块"："ESNext"表示tsc，如果您使用webpack或其他构建工具，请为ts-node设置一个覆盖。

{
  "compilerOptions": {
    "target": "ES2020",
    "module": "NodeNext",
    "moduleResolution": "NodeNext",
    "esModuleInterop": true,
    "types": ["node"],
    "allowSyntheticDefaultImports": true,
    "rootDir": "./"
  },
  "ts-node": {
    "compilerOptions": {
      "module": "CommonJS"
    }
  }
}

在这一点上我也试着加上

{
  "compilerOptions": {
    "module": "ESNext" // or ES2015, ES2020
  },
  "ts-node": {
    // Tell ts-node CLI to install the --loader automatically, explained below
    "esm": true
  }
}

第三个选项是安装tsconfig-paths包，它也没有www.example.com所有情况下，错误仍然与之前编写的相同。help.in all cases, the error remained the same as it was written before.
