使用ts-loader的npm文档建议安装typescript，webpack文档中的官方Typescript guide也是如此，但实际上没有提供任何理由。对我来说，一切都是成功地建立没有typescript被安装。我错过了什么？
我当前的设置：
webpack.config.js

const webpack = require("webpack");
const HtmlWebpackPlugin = require("html-webpack-plugin");

module.exports = {
    // mode: 'development',
    entry: './src/index.ts',
    module: {
        rules: [
            {
                test: /\.ts$/,
                use: 'ts-loader'
            }
        ]
    },
    output: {
        filename: "bundle.js",
    },
    plugins: [
        new HtmlWebpackPlugin(),
        new webpack.ProgressPlugin()
    ]
}

package.json

{
  ...
  "scripts": {
    "webpack": "webpack",
    "build:dev": "npm run webpack -- --mode development",
    "start": "npm run webpack serve -- --mode development"
  },
  "author": "ranemihir",
  "license": "ISC",
  "devDependencies": {
    "html-webpack-plugin": "^5.5.3",
    "ts-loader": "^9.4.4",
    "webpack": "^5.88.2",
    "webpack-cli": "^5.1.4",
    "webpack-dev-server": "^4.15.1"
  }
}
