Module not found: Error: Can't resolve 'util' in 'Z:\vue-mange-master\node_modules\forever-agent' BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default. This is no longer the case. Verify if you need this module and configure a polyfill for it.

这个错误是由于webpack升级到5之后,不再默认包含node.js核心模块的polyfills导致的。在你的项目中,`forever-agent`这个模块依赖了`util`模块,而webpack无法找到它。
解决这个问题的方法是手动在webpack配置中添加一个resolve别名,将缺失的模块指向一个可用的polyfill。具体操作步骤如下:
1. 打开webpack配置文件(通常是`webpack.config.js`)。
2. 在配置文件中找到`resolve`字段,如果没有则手动添加。
3. 在`resolve`字段下添加一个别名配置,将`util`指向一个可用的polyfill。例如:
```javascript
resolve: {
alias: {
util: require.resolve('util/')
}
}
```
4. 保存配置文件并重新运行webpack构建,应该就能解决这个错误了。
希望这能帮到你!如果有任何其他问题,请随时提问。

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。
Module not found: Error: Can't resolve 'os' in 'D:\car\ceshi\cess2\node_modules\python-shell'
根据提供的引用内容,出现了两个不同的错误信息。第一个引用中出现了"Module not found: Error: Can’t resolve ‘swiper/vue’ in ‘D:\前端\Git\Git\Vue\music\node_modules\vue-awesome-swiper’"的错误,第二个引用中出现了"Module not found: Error: Can‘t resolve ‘path‘ in ‘/Users/wangabai/Desktop/学习/vue/code/vue3.2-element"的错误。
针对第一个引用中的错误,可以尝试删除"vue-awesome-swiper"文件夹,然后重新安装该模块。具体操作如下:
```shell
去node_modules中删除文件夹vue-awesome-swiper
```
针对第二个引用中的错误,可以尝试检查是否正确引入了"path"模块,并确保该模块已经正确安装。具体操作如下:
```shell
