chore: 升级项目依赖和构建工具，迁移至Webpack 5.x

主要变更包括：
1. 更新Babel配置，使用@babel/preset-env和@babel/plugin-transform-object-rest-spread。
2. 升级Webpack及相关插件，使用MiniCssExtractPlugin替代ExtractTextPlugin。
3. 更新package-lock.json和package.json，调整依赖版本。
4. 修改README.md，更新项目简介和环境要求。
5. 代码格式优化和错误处理增强，提升构建和开发体验。

+
+项目已从Webpack 3.x升级到Webpack 5.x，主要解决了以下问题：
+1. 添加了Node.js核心模块（如Buffer、process）的polyfill
+2. 配置了fallback解析路径
+3. 使用ProvidePlugin全局提供对象

 ## 常见问题
 
-### Q: 为什么必须使用Node.js 12.22.12？
+### Q: 为什么使用Node.js 18.x版本会出现警告？
-A: 项目依赖的某些包（如node-sass 4.12.0）对Node.js版本有严格要求，使用其他版本可能导致编译错误。
+A: 主要是node-sass和pkcs7包的兼容性问题，这些警告不影响项目运行。未来计划迁移到sass/sass-embedded并更新pkcs7包。
+
+### Q: 如何解决依赖安装冲突？
+A: 建议使用`npm install --legacy-peer-deps`命令安装依赖。
 
 ### Q: 如何切换Node.js版本？
 A: 推荐使用nvm（Node Version Manager）来管理Node.js版本：
 ```bash
 # 安装指定版本
-nvm install 12.22.12
+nvm install 18.12.1
-nvm use 12.22.12
+nvm use 18.12.1

+# Webpack 3 升级到 Webpack 5 详细计划
+
+## 升级背景
+当前项目使用 Webpack 3.6.0，需要升级到 Webpack 5 以支持 Node.js 18，并提升构建性能和安全性。
+
+## 升级前准备
+1. 备份项目代码和 `package.json` 文件
+2. 确保已安装 Node.js 18+（当前计划使用版本）
+3. 了解 Webpack 3 与 Webpack 5 的主要差异
+
+## 升级步骤
+
+### 1. 卸载旧依赖
+```bash
+npm uninstall webpack webpack-cli webpack-dev-server webpack-merge extract-text-webpack-plugin
+```
+
+### 2. 安装新依赖
+```bash
+npm install webpack@5.88.2 webpack-cli@5.1.4 webpack-dev-server@4.15.1 webpack-merge@5.9.0 mini-css-extract-plugin@2.7.6 --save-dev
+npm install html-webpack-plugin@5.5.3 --save-dev
+npm install vue-loader@15.10.1 --save-dev
+```
+
+### 3. 更新 package.json 脚本
+修改 `package.json` 中的 scripts 部分:
+```json
+{
+  "scripts": {
+    "dev": "webpack serve --config build/webpack.dev.conf.js --host 0.0.0.0",
+    "build": "node build/build.js"
+  }
+}
+```
+
+### 4. 修改 Webpack 配置文件
+
+#### 4.1 修改 webpack.base.conf.js
+- 添加 VueLoaderPlugin
+- 更新 module.rules 配置
+- 调整输出配置
+
+#### 4.2 修改 webpack.dev.conf.js
+- 更新 devServer 配置
+- 修改插件配置
+
+#### 4.3 修改 webpack.prod.conf.js
+- 替换 extract-text-webpack-plugin 为 mini-css-extract-plugin
+- 更新优化配置
+- 移除过时插件
+
+### 5. 解决可能的兼容性问题
+- 处理 Babel 配置
+- 更新其他 loader 版本
+- 解决依赖冲突
+
+## 主要变化点
+1. Webpack 5 内置更多功能，减少对第三方插件的依赖
+2. 开发服务器配置变化 (webpack-dev-server -> webpack serve)
+3. 提取 CSS 的插件变化 (extract-text-webpack-plugin -> mini-css-extract-plugin)
+4. 模块解析和优化配置的变化
+5. 缓存机制改进
+
+## 可能遇到的问题及解决方案
+1. **Node.js 版本兼容问题**：确保使用 Node.js 18+
+2. **插件不兼容**：逐一替换为 Webpack 5 兼容版本
+3. **配置语法变化**：更新配置文件以符合 Webpack 5 语法
+4. **依赖冲突**：使用 npm ls 检查并解决冲突
+
+## 测试计划
+1. 升级后运行 `npm run dev` 测试开发环境
+2. 运行 `npm run build` 测试生产构建
+3. 检查应用功能是否正常
+4. 验证构建输出文件大小和性能
+
+## 实际升级问题及解决方案
+
+在实际升级过程中，我们遇到了以下问题并成功解决：
+
+### 1. Node.js 核心模块未定义问题 (Buffer, process)
+
+**问题描述**：升级到 Webpack 5 后，浏览器中出现 `Buffer is not defined` 和 `process is not defined` 错误。
+
+**原因**：Webpack 5 不再自动 polyfill Node.js 核心模块，需要手动添加。
+
+**解决方案**：
+1. 安装必要的 polyfill 包：
+   ```bash
+   npm install buffer@6.0.3 process@0.11.10 vm-browserify@1.1.2 --save
+   ```
+
+2. 在 webpack.base.conf.js 中添加以下配置：
+   ```javascript
+   const webpack = require('webpack');
+   
+   module.exports = {
+     // ... 其他配置
+     resolve: {
+       fallback: {
+         buffer: require.resolve('buffer/'),
+         process: require.resolve('process/'),
+         vm: require.resolve('vm-browserify')
+       }
+     },
+     plugins: [
+       // ... 其他插件
+       new webpack.ProvidePlugin({
+         Buffer: ['buffer', 'Buffer'],
+         process: 'process/browser'
+       })
+     ]
+   };
+   ```
+
+### 2. Node.js 18 与 node-sass 兼容性问题
+
+**问题描述**：在 Node.js 18 环境下，使用旧版本 node-sass 导致编译错误。
+
+**原因**：node-sass 4.x 不兼容 Node.js 18。
+
+**解决方案**：
+1. 升级 node-sass 到最新版本：
+   ```bash
+   npm install node-sass@9.0.0 --save-dev --legacy-peer-deps
+   ```
+
+2. 使用 `--legacy-peer-deps` 标志解决与 webpack 5 的依赖冲突。
+
+> 注意：node-sass 已被弃用，建议未来迁移到 sass 或 sass-embedded。
+
+### 3. pkcs7 包引擎版本不兼容警告
+
+**问题描述**：安装依赖时出现 pkcs7 包要求 node@^0.10 的警告。
+
+**原因**：项目依赖的 pkcs7 包版本过旧，与 Node.js 18 不兼容。
+
+**解决方案**：
+- 目前可以忽略此警告，不影响项目运行。
+- 建议未来更新此包到兼容版本。
+
+### 4. 依赖安装冲突
+
+**问题描述**：安装新依赖时出现多个包版本冲突。
+
+**原因**：不同包对同一个依赖的版本要求不一致。
+
+**解决方案**：
+- 使用 `npm install --legacy-peer-deps` 命令安装依赖：
+  ```bash
+  npm install --legacy-peer-deps
+  ```
+
+### 5. webpack-dev-server 配置变化
+
+**问题描述**：升级后开发服务器无法正常启动。
+
+**原因**：webpack-dev-server 4.x 配置方式有较大变化。
+
+**解决方案**：
+1. 更新 webpack.dev.conf.js 中的 devServer 配置：
+   ```javascript
+   devServer: {
+     host: '0.0.0.0',
+     port: 8080,
+     client: {
+       overlay: { warnings: false, errors: true },
+     },
+     historyApiFallback: true,
+     proxy: {
+       '/api': {
+         target: 'http://sz-test.shengzhevictor.com',
+         changeOrigin: true
+       }
+     }
+   }
+   ```
+
+2. 更新 package.json 中的 dev 脚本：
+   ```json
+   {
+     "scripts": {
+       "dev": "webpack serve --config build/webpack.dev.conf.js --host 0.0.0.0"
+     }
+   }
+   ```
+
+### 6. resolve.fallback 配置引号问题
+
+**问题描述**：Webpack 5 配置验证错误，提示 resolve.fallback 配置中的属性名不能带引号。
+
+**原因**：Webpack 5 对配置格式有更严格的要求，resolve.fallback 中的属性名应该是标识符而非字符串。
+
+**解决方案**：
+修改 webpack.base.conf.js 文件，移除 resolve.fallback 配置中各属性名的单引号：
+```javascript
+resolve: {
+  fallback: {
+    crypto: require.resolve('crypto-browserify'),
+    stream: require.resolve('stream-browserify'),
+    buffer: require.resolve('buffer/'),
+    process: require.resolve('process/'),
+    vm: require.resolve('vm-browserify')
+  }
+}
+```
+
+### 7. devtool 配置格式问题
+
+**问题描述**：Webpack 5 配置验证错误，提示 configuration.devtool 不符合模式 "^(inline-|hidden-|eval-)?(nosources-)?(cheap-(module-)?)?source-map(-debugids)?$"
+
+**原因**：Webpack 5 对 devtool 配置格式有严格要求，不再支持以 "#" 开头的格式。
+
+**解决方案**：
+修改 config/index.js 文件，将 build.devtool 的值从 "#source-map" 改为 "source-map"：
+```javascript
+build: {
+  // ... 其他配置
+  devtool: 'source-map',
+  // ... 其他配置
+}
+```
+
+## 升级总结
+
+1. 成功将 Webpack 从 3.6.0 升级到 5.88.2
+2. 解决了 Node.js 18 兼容性问题，使项目能够在现代 Node.js 环境下运行
+3. 添加了必要的 Node.js 核心模块 polyfill
+4. 解决了依赖冲突和插件兼容性问题
+5. 更新了构建配置以符合 Webpack 5 语法
+
+虽然升级过程中遇到了一些挑战，但通过逐一解决问题，最终成功完成了升级，为项目后续的维护和性能优化奠定了基础。
