webpack not working, what to do?

Question

JavaScript

const path = require("path");
const HTMLWebpackPlugin = require("html-webpack-plugin");

module.exports = {
  entry: "./src/index.js",
  output: {
    filename: "bundle.js",
    path: path.resolve(__dirname, "dist"),
  },
  devServer: {
    port: 3000,
  },
  plugins: [
    new HTMLWebpackPlugin({
      template: "./src/index.html",
    }),
  ],
};

Here is the minimum build, after I write webpack in the terminal, it gives

One CLI for webpack must be installed. These are recommended choices, delivered as separate packages:
- webpack-cli ( https://github.com/webpack/webpack-cli )
The original webpack full-featured CLI.
We will use "npm" to install the CLI via "npm install -D".
Do you want to install 'webpack-cli' (yes/no): n
You need to install 'webpack-cli' to use webpack via CLI.
You can also install the CLI manually.
