当我尝试对项目进行webpack打包时，我得到<link rel=stylesheet href=[object Object]>这个错误，我期望的CSS样式为./styles.css。 我是webpack的新手，任何人都可以帮助我解决此问题。提前致谢。

这是我正在处理的文件：

webpack.config.common.js

const path = require('path');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');
//const HtmlWebpackPlugin = require('html-webpack-plugin')

module.exports = {
  entry: './src/index.js',output: {
    filename: '[name].[contenthash].js',filename: '[name].[contenthash].js',path: path.resolve(__dirname,'dist'),},plugins: [
    new CleanWebpackPlugin(),//    new HtmlWebpackPlugin({
    //      filename: 'index.html',//      inject: true,//      template: path.resolve(__dirname,'src','index.html'),//    }),],module: {
    rules: [
      {
        test: /\.(js|jsx)$/,exclude: /[\\/]node_modules[\\/]/,use: {
          loader: 'babel-loader',};

Index.js文件

import './index.css';
import styles from './css/bootstrap.min.css';
import customstyles from './scss/main.css';

import html from './index.html';

webpack.config.prod.js

const commonconfig = require('./webpack.config.common');
const merge = require('webpack-merge');
var HtmlWebpackPlugin = require('html-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const OptimizeCssAssetsplugin = require('optimize-css-assets-webpack-plugin');
const TerserPlugin = require('terser-webpack-plugin');
const ImageminWebpWebpackPlugin = require('imagemin-webp-webpack-plugin');
const ImageminWebP = require('imagemin-webp');

module.exports = merge(commonconfig,{
  mode: 'production',devtool: 'source-map',module: {
    rules: [
      {
        test: /\.html$/i,use: ['file-loader?name=[name].[ext]','extract-loader','html-loader'],{
        test: /\.css$/i,use: [MiniCssExtractPlugin.loader,'css-loader'],// Image Compression
      {
        test: /\.(gif|png|jpe?g|svg)$/i,use: [
          'file-loader',{
            loader: 'image-webpack-loader',options: {
              mozjpeg: {
                progressive: true,quality: 65,// optipng.enabled: false will disable optipng
              optipng: {
                enabled: false,pngquant: {
                quality: [0.65,0.9],speed: 4,gifsicle: {
                interlaced: false,// the webp option will enable WEBP
              webp: {
                quality: 75,plugins: [
    //new HtmlWebpackPlugin(),new MiniCssExtractPlugin({
      filename: '[name].[contenthash].css',}),new ImageminWebpWebpackPlugin({
      plugins: [
        ImageminWebP({
          quality: 75,optimization: {
    minimizer: [
      new OptimizeCssAssetsplugin({
        cssprocessorOptions: {
          map: {
            inline: false,annotation: true,new TerserPlugin({
        // Use multi-process parallel running to improve the build speed
        // Default number of concurrent runs: os.cpus().length - 1
        parallel: true,// Enable file caching
        cache: true,sourceMap: true,});
