-# 身体平衡评估系统 - 后端打包说明
-
-本文档说明如何将后端Python应用程序打包成独立的exe可执行文件。
-
-## 📋 打包前准备
-
-### 1. 环境要求
-- Python 3.8+ (推荐 3.9-3.11)
-- Windows 10/11 操作系统
-- 至少 2GB 可用磁盘空间
-
-### 2. 依赖检查
-确保以下核心依赖已安装：
-```bash
-pip install Flask Flask-CORS Flask-SocketIO
-pip install numpy opencv-python psutil
-pip install PyInstaller
-```
-
-## 🚀 快速打包
-
-### 方法一：使用批处理脚本（推荐）
-1. 在backend目录下双击运行 `build_backend.bat`
-2. 脚本会自动完成所有打包步骤
-3. 等待打包完成
-
-### 方法二：手动打包
-1. 打开命令提示符，切换到backend目录
-2. 运行打包脚本：
-   ```bash
-   python build_exe.py
-   ```
-
-### 方法三：直接使用PyInstaller
-```bash
-# 生成spec文件
-pyinstaller --onefile --windowed --name=BodyBalanceBackend app.py
-
-# 或使用自定义spec文件
-pyinstaller backend.spec --clean --noconfirm
-```
-
-## 📁 输出文件结构
-
-打包完成后，在 `dist/` 目录下会生成：
-
-```
-dist/
-├── BodyBalanceBackend.exe     # 主可执行文件
-├── start_backend.bat          # 启动脚本
-├── config.ini                 # 配置文件
-├── config.json               # JSON配置文件
-└── logs/                     # 日志目录（运行时创建）
-```
-
-## 🔧 配置说明
-
-### PyInstaller配置 (backend.spec)
-- **--onefile**: 打包成单个exe文件
-- **--windowed**: 隐藏控制台窗口（可选）
-- **--add-data**: 包含数据文件
-- **--add-binary**: 包含二进制文件（如DLL）
-- **--hidden-import**: 包含隐式导入的模块
-
-### 包含的文件
-- 配置文件：`config.ini`, `config.json`
-- 动态库：`dll/k4a.dll`（如果存在）
-- 数据目录：`data/`, `captured_images/`, `tests/`
-
-## 🚀 部署和运行
-
-### 1. 部署到目标机器
-1. 将整个 `dist/` 文件夹复制到目标机器
-2. 确保目标机器安装了必要的运行时库
-
-### 2. 运行方式
-
-**方式一：直接运行**
-```bash
-BodyBalanceBackend.exe
-```
-
-**方式二：使用启动脚本**
-```bash
-start_backend.bat
-```
-
-**方式三：命令行运行**
-```bash
-cd dist
-BodyBalanceBackend.exe
-```
-
-### 3. 访问服务
-- 服务器地址：`http://localhost:5000`
-- 健康检查：`http://localhost:5000/health`
-- API文档：`http://localhost:5000/api/health`
-
-## 🔍 故障排除
-
-### 常见问题
-
-**1. 打包失败**
-- 检查Python版本是否兼容
-- 确保所有依赖已正确安装
-- 检查磁盘空间是否充足
-
-**2. exe运行失败**
-- 检查是否缺少Visual C++ Redistributable
-- 查看logs目录下的错误日志
-- 确保配置文件存在且格式正确
-
-**3. 模块导入错误**
-- 在spec文件中添加缺失的模块到 `hiddenimports`
-- 检查第三方库的兼容性
-
-**4. 文件路径问题**
-- 确保所有相对路径正确
-- 检查数据文件是否正确包含
-
-### 调试方法
-
-**1. 启用控制台输出**
-修改spec文件中的 `console=True`
-
-**2. 查看详细日志**
-```bash
-BodyBalanceBackend.exe --debug
-```
-
-**3. 测试模式运行**
-```bash
-python app.py
-```
-
-## 📝 自定义打包
-
-### 修改打包配置
-编辑 `build_exe.py` 文件，可以自定义：
-- 输出文件名
-- 包含的文件和目录
-- 隐式导入的模块
-- 图标文件
-
-### 添加新的依赖
-1. 在 `requirements_build.txt` 中添加新依赖
-2. 在spec文件的 `hiddenimports` 中添加模块名
-3. 重新打包
-
-## 🔒 安全注意事项
-
-1. **配置文件安全**：确保配置文件中不包含敏感信息
-2. **网络安全**：默认绑定所有接口(0.0.0.0)，生产环境建议修改
-3. **文件权限**：确保exe文件有适当的执行权限
-
-## 📞 技术支持
-
-如果遇到问题，请检查：
-1. 日志文件：`logs/backend.log`
-2. 系统要求是否满足
-3. 依赖版本是否兼容
-
----
-
-**注意**：首次打包可能需要较长时间，请耐心等待。建议在虚拟环境中进行打包以避免依赖冲突。
