La configuración de Webpack escrita en TypeScript arroja un error sobre import

Recientemente he intentado migrar mi configuración de Webpack escrita en JavaScript a TypeScript. Desafortunadamente, tengo muchas dificultades con esto. He escrito un archivo de configuración mínimo para webpack con el que empezar, por lo que faltan algunas partes. Mi webpack.config.ts se ve así:

import webpack from "webpack";

const config: webpack.Configuration = {
    entry: {
        bookmarklet: 'bookmarklet.ts'
    },
    output: {
        filename: '[name].js',
        path: __dirname + '/dist'
    }
}

export default config;

Tengo un tsconfig.json que contiene:

{
    "compilerOptions": {
        "module": "ESNext",
        "target": "ES6",
        "lib": ["ES6", "dom"],
        "strict": true,
        "isolatedModules": true,
        "esModuleInterop": true,
        "moduleResolution": "Node",
        "skipLibCheck": true,
        "noUnusedLocals": true,
        "noUnusedParameters": true,
        "removeComments": false
    }
}

El package.json contiene:

{
  "name": "bookmarklets",
  "version": "0.0.1",
  "description": "A collection of bookmarklets",
  "license": "MIT",
  "scripts": {
    "build": "webpack --config webpack.config.ts"
  },
  "devDependencies": {
    "@types/node": "^14.10.0",
    "@types/webpack": "^4.41.22",
    "bookmarklet-wrapper-webpack-plugin": "^1.0.1",
    "ts-node": "^9.0.0",
    "webpack": "^4.44.1",
    "webpack-cli": "^3.3.12"
  }
}

Al ejecutar yarn build se produce el siguiente error:

yarn run v1.22.5
webpack --config webpack.config.ts
/home/codespace/workspace/zli-bookmarklets/webpack.config.ts:1

¿Cómo encapsulo mi configuración dentro de un módulo? ¿Cuál es la razón del error?

Actualizar

También he probado el siguiente tsconfig.json como se sugiere aquí:

{
    "compilerOptions": {
        "module": "CommonJS",
        "target": "ES5",
        "esModuleInterop": true,
    }
}

Desafortunadamente ocurre el mismo error.

Respuesta #1

he resuelto con

{
    "compilerOptions": {...},
    "ts-node": {
        "compilerOptions": {
        "module": "CommonJS"
     }
  }
}
