Field 'browser' doesn't contain a valid alias configuration when I changed the import path using @

When I changed the vue component import from:

import Options from './components/Translator.vue'

to:

import Options from '@/popup/components/Translator.vue'

shows error:

ERROR in ./src/popup/App.vue?vue&type=script&lang=ts (./node_modules/ts-loader/index.js??clonedRuleSet-1!./node_modules/vue-loader/dist/index.js??ruleSet[1].rules[8].use[0]!./src/popup/App.vue?vue&type=script&lang=ts) 3:0-67

webpack 5.67.0 compiled with 1 error in 116 ms

Where is the browser? I search my whole project and did not found this. why would I set the browser alias? what should I do to avoid this problem? this is the webpack 5.x alias config:

resolve: {
    extensions: ['.tsx', '.ts', '.js'],
    alias: {
        // https://stackoverflow.com/questions/50805384/module-not-found-error-cant-resolve-vue-path-not-correct
        vue: 'vue/dist/vue.esm-bundler.js',
        '@': path.resolve(__dirname, 'src'),
    },
  },

Today I face the same problem again and tweak the config like this:

resolve: {
      extensions: ['.tsx', '.ts', '.js'],
      alias: {
          vue: 'vue/dist/vue.esm-bundler.js',
          process: 'process/browser',
          @: path.resolve(__dirname, 'src'),
      },
    },

still did not work at all. This is my full webpack config:

  const path = require('path');
  const webpack = require( 'webpack' );
  const MiniCssExtractPlugin = require( 'mini-css-extract-plugin');
  const HtmlWebpackPlugin = require( 'html-webpack-plugin');
  const CopyPlugin = require("copy-webpack-plugin");
  const { VueLoaderPlugin } = require("vue-loader");

  module.exports = {
    entry : {
      'popup/popup' : './src/popup/',
      'background/background': './src/background' 
    } ,
    resolve: {
      extensions: ['.tsx', '.ts', '.js'],
      alias: {
          vue: 'vue/dist/vue.esm-bundler.js',
          process: 'process/browser',
          '@': path.resolve(__dirname, 'src'),
      },
    },
    output : {
      path : path.resolve(__dirname, '../../bundle') ,
      filename : '[name].js'
    },
    module : {
      rules : [
        {
          test: /\.ts$/,
          loader: 'ts-loader',
          options: {
            appendTsSuffixTo: [/\.vue$/]
          },
          exclude: /node_modules|\.d\.ts$/
        },
        {
          test: /\.d\.ts$/,

        },
        {
          test: /\.vue$/,
          loader: 'vue-loader'
        },
        {
          test : /\.js$/ ,
          exclude : [ /node_modules(?!(\/|\\?\\)(translation\.js|selection-widget|connect\.io|chrome-env)\1)/ ] ,
          loader : 'babel-loader'
        } ,
        {
          test: /\.css$/i,
          use: [MiniCssExtractPlugin.loader, "css-loader"],
        },
        {
          test : /\.(scss)$/ ,
          use: [MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader']
        }
      ]
    },
    plugins : [
      new webpack.ProvidePlugin({
        process: 'process/browser',
      }),
      new VueLoaderPlugin(),
      new CopyPlugin({
        patterns: [
          { from: "src/manifest.json", to: "manifest.json" },
          { from: "src/resource/image", to: "resource/image" },
        ],
      }),
      new MiniCssExtractPlugin({
        filename: "[name].css",
        chunkFilename: "[id].css",
      }),
      new HtmlWebpackPlugin({
        filename: 'popup/popup.html',
        template: 'src/popup/index.html'
      }),
      new webpack.DefinePlugin({
        __VUE_OPTIONS_API__: false,
        __VUE_PROD_DEVTOOLS__: false,
      }),
    ]
  };
