 ### C. 解决方案
 - 文档创建和 git 操作可在 AI 环境中完成
 - 构建验证（`npm run lint`、`npm run build`、`npm start`）需由用户在本地开发环境执行，或 AI 提供精确命令由用户自行运行
-- 在经验记录中标注此限制，提醒后续流程
+- **实际解决**: 用户提供了 sudo 权限和密码后，AI 通过 NodeSource 安装了 Node.js 22.x（`curl -fsSL https://deb.nodesource.com/setup_22.x | sudo bash` + `sudo apt install -y nodejs`），随后成功执行了完整部署流程
+- 在经验记录中标注此限制和解决方案，提醒后续流程
 
 ### D. 后续如何避免问题
 - 每次执行阶段 6 和阶段 9 前，先检查 `which npm`
-- 如 npm 不可用，向用户明确说明需手动执行的命令，并提供复制粘贴格式
+- 如 npm 不可用，向用户申请 sudo 权限安装 Node.js，或使用项目预设的容器/CI 环境
+- 如用户无法提供 sudo，则提供精确的手动执行命令清单
 - 考虑在 CI/CD 流程中统一构建环境
