这个错误提示是由 webpack 编译器报出的。从错误信息看，是在编译 lop 和 mammoth 模块时出现了找不到 util 和 path 模块的错误。这是由于 webpack 5 不再默认引入 Node.js 核心模块的 polyfill，需要开发者手动引入或安装相应的 polyfill。

解决方法如下：

1. 安装 polyfill

您可以使用以下命令安装相应的 polyfill 模块：

npm install util path-browserify --save-dev

2. 配置 webpack

在 webpack 配置文件中添加以下代码：

resolve: {
  fallback: {
    "util": require.resolve("util/"),
    "path": require.resolve("path-browserify"),
  },
}

这样就会在编译时自动引入相应的 polyfill 模块，解决这个错误。

这个错误可能是由于 postcss-loader 和 css-loader 版本不兼容导致的。你可以尝试升级这两个 loader 的版本，或者降低它们的版本，看看是否解决了这个问题。

另外，你可以尝试在 webpack 配置中添加一个 postcss 配置，指定使用的 postcss 版本，例如：

module.exports = {
  // ...
  module: {
    rules: [
      // ...
      {
        test: /\.css$/,
        use: [
          'style-loader',
          'css-loader',
          {
            loader: 'postcss-loader',
            options: {
              postcssOptions: {
                plugins: [
                  // 指定使用的 postcss 版本
                  require('postcss')({
                    // ...
                  })
                ]
              }
            }
          }
        ]
      }
    ]
  }
}

希望能帮助到你！

这个报错是因为在使用Vue Router时，导入的Vue Router版本与当前项目中的Vue版本不匹配导致的。具体来说，Vue Router中使用了Vue 3的语法而当前项目中使用的是Vue 2，所以会出现一些语法上的错误。解决方法是将Vue Router更新到与当前项目中使用的Vue版本相匹配的版本。
