copy-webpack-plugin 错误：主机定义的选项无效

Question

使用 copy-webpack-plugin 后构建失败。 webpack 和插件版本已经过兼容性测试（webpack5 cwp10） 我的想法不多了:( 有没有人碰到过熟悉的东西？ 这可能是跨模块兼容性问题吗？

进一步提供错误日志和配置代码 提前致谢

错误是

使用的配置是（webpack.config.js）

const webpack = require('webpack');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
const CopyPlugin = require('copy-webpack-plugin');
const path = require('path');

module.exports = (env) => [
  {
    mode: 'production',
    entry: './js/background.js',
    output: {
      path: path.resolve(__dirname, 'dist'),
      publicPath: '/',
      filename: 'background.js',
    },
  },
  {
    mode: 'production',
    entry: {
      './js/login': './js/login.js',
      './js/search': './js/search.js',
      './js/options': './js/options.js',
    },
    output: {
      path: path.resolve(__dirname, 'dist'),
      filename: '[name].js',
      publicPath: '/',
    },
    module: {
      rules: [
        {
          test: /\.(scss|css)$/,
          use: [MiniCssExtractPlugin.loader, "css-loader",
            {
              loader: "sass-loader",
            }
          ]
        },
        {
          test: /\.(png|svg|jpg|jpeg|gif)$/i,
          type: 'asset/resource',
          generator: {
            filename: 'styles/images/[hash][ext][query]'
          }
        },
        {
          test: /\.(woff|woff2|eot|ttf|otf)$/i,
          type: 'asset/resource',
          generator: {
            filename: 'styles/[hash][ext][query]'
          }
        },
      ]
    },
    plugins: [
      new CopyPlugin({
        patterns: [
          {
            from: '/extension-icons/*'
          }
        ],
      }),
      new webpack.DefinePlugin({
        BUILD_FOR: JSON.stringify(env.custom)
      }),
      new MiniCssExtractPlugin({
        filename: ({ chunk }) => `${chunk.name.replace('/js/', '/styles/')}.css`,
      }),
    ],
  }
];

Answer 1

插件版本 10 开始使用动态导入的 ES 模块。这仍然在各种工具中得到了一些低于标准的支持。例如。 Yarn 似乎不能很好地处理它（但基于 npm 的设置也可能会损坏）

github 上的相关错误报告：

• https://github.com/webpack-contrib/copy-webpack-plugin/issues/652
• https://github.com/webpack-contrib/copy-webpack-plugin/issues/653
• https://github.com/webpack-contrib/copy-webpack-plugin/issues/643

官方回应：问题出在其他工具上，而不是插件本身。

看起来最好的方法是降级到 v9，正如上面一些人已经提到的那样。
