当我尝试对我的项目进行 webpack 时，我收到了这个错误，这是<link rel=stylesheet href=[object Object]>我对 CSS 样式的预期输出 ./styles.css。我是 webpack 的新手，谁能帮我解决这个问题。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',
        },
      },
    ],
  },
};

索引.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');

const TerserPlugin = require('terser-webpack-plugin');
const ImageminWebpWebpackPlugin = require('imagemin-webp-webpack-plugin');

module.exports = merge(commonConfig, {

      },

      {
        test: /\.css$/i,
        use: [MiniCssExtractPlugin.loader, 'css-loader'],
      },

      // Image Compression

              },
              // optipng.enabled: false will disable optipng
              optipng: {

              },
              pngquant: {

              },
            },
          },
        ],
      },
    ],
  },

  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,
      }),
    ],
  },
});
