Why is vue.config.js not working?

Question

Vue.js

I'm trying to start using stylus in Vue, the documentation says that you need to write a config for webpack, it says that to work with webpack on Vue, you need to write everything in vue.config.js, in fact, here it is:

const VueLoaderPlugin = require('vue-loader/lib/plugin')

module.exports = {

  configureWebpack: {
    mode: 'development',
    module: {
      rules: [
        {
          test: /\.vue$/,
          loader: 'vue-loader'
        },
        {
          test: /\.css$/,
          use: [
            'vue-style-loader',
            {
              loader: 'css-loader',
              options: {
                modules: true,
                localIdentName: '[local]_[hash:base64:8]'
              }
            }
          ]
        },
        {
          test: /\.styl(us)?$/,
          use: [
            'vue-style-loader',
            {
              loader: 'css-loader',
              options: {
                modules: true,
                localIdentName: '[local]_[hash:base64:8]'
              }
            },
            'stylus-loader'
          ]
        }
      ]
    },
    plugins: [
      new VueLoaderPlugin()
    ]
  }
}

But when I try to run the application, an error occurs:

Obviously you didn't install vue-loader
