解决AWS Amplify构建中的peer dependency冲突问题
问题背景
本地开发环境测试变更无问题，但部署到AWS Amplify测试环境时构建失败，出现npm依赖解析错误：

已尝试的无效操作
- 使用
--force和--legacy-peer-deps参数运行构建，未解决依赖冲突 - 将assemble降级到styles peer dependency指定的
0.3.11版本，本地构建正常，但Amplify构建出现lock文件不同步错误：
2022-11-28T19:38:40.756Z [WARNING]: npm ERR! 2022-11-28T19:38:40.756Z [WARNING]: code EUSAGE 2022-11-28T19:38:40.760Z [WARNING]: npm 2022-11-28T19:38:40.760Z [WARNING]: ERR! npm ERR! `npm ci` can only install packages when your package.json and package-lock.json or npm-shrinkwrap.json are in sync.

- 卸载assemble和styles，测试环境构建仍报相同错误
- 确认package.json和package-lock.json已数月未修改，且此前多次构建成功
环境信息
- 本地开发环境：node v16.13.1，npm v8.1.2
- Amplify构建环境：默认Node 16镜像（未指定具体npm版本）
有效解决方案
方案1：指定Amplify使用与本地一致的npm版本并启用legacy-peer-deps
Amplify默认的Node 16镜像可能搭载了更高版本的npm，其peer依赖解析逻辑与本地npm 8.1.2存在差异。修改Amplify构建命令：
- 进入AWS Amplify控制台，找到目标应用的Build settings
- 在Build commands中，将原有的
npm install替换为：npm install -g npm@8.1.2 && npm install --legacy-peer-deps - 保存配置并重新触发构建
方案2：修复lock文件同步问题（针对降级assemble的场景）
若选择降级assemble到兼容版本：
- 本地执行命令安装指定版本：
npm install assemble@~0.3.11 - 确认package.json和package-lock.json均已更新，将两者同步提交到代码仓库
- 重新触发Amplify构建，此时
npm ci会使用同步的lock文件完成安装
方案3：使用npm overrides强制解决依赖冲突（npm 8.3+支持）
通过package.json的overrides字段，强制styles适配当前项目的assemble版本：
- 在package.json中添加以下配置：
"overrides": { "styles": { "assemble": "^0.24.3" } } - 本地执行
npm install更新lock文件 - 提交更新后的package.json和package-lock.json，重新触发构建
方案4：清理Amplify构建缓存
旧缓存可能残留异常依赖，导致构建失败：
- 在Amplify控制台的构建页面，点击Redeploy this version
- 选择Clear cache and deploy选项，等待重新构建
