+# PyQt5 平台插件问题完全解决方案
+
+## 问题描述
+在使用PyQt5时，可能会遇到以下错误：
+```
+qt.qpa.plugin: Could not find the Qt platform plugin "cocoa" in ""
+This application failed to start because no Qt platform plugin could be initialized.
+```
+
+## 解决方案
+
+### 方法一：一键修复（推荐）
+运行完整的修复脚本：
+```bash
+python fix_pyqt5_complete.py
+```
+
+### 方法二：手动修复
+1. **清理现有安装**
+```bash
+pip uninstall PyQt5 PyQt5-Qt5 PyQt5-sip -y
+rm -rf /Users/maziang/Documents/CodingWorkPlace/Code/Curriculum_Design/.venv/lib/python3.9/site-packages/PyQt5*
+```
+
+2. **重新安装**
+```bash
+pip install PyQt5==5.15.10 --force-reinstall --no-cache-dir
+```
+
+3. **设置环境变量**
+```bash
+source set_pyqt5_env.sh
+```
+
+### 方法三：安全安装
+使用安全安装脚本：
+```bash
+python install_pyqt5_safe.py
+```
+
+## 预防措施
+
+### 1. 在main.py中集成环境设置
+确保你的 `main.py` 包含了增强的Qt插件路径设置函数。
+
+### 2. 创建启动脚本
+创建 `start_app.sh`：
+```bash
+#!/bin/bash
+# PyQt5应用程序启动脚本
+
+# 设置环境变量
+export QT_PLUGIN_PATH="/Users/maziang/Documents/CodingWorkPlace/Code/Curriculum_Design/.venv/lib/python3.9/site-packages/PyQt5/Qt5/plugins"
+export QT_QPA_PLATFORM_PLUGIN_PATH="/Users/maziang/Documents/CodingWorkPlace/Code/Curriculum_Design/.venv/lib/python3.9/site-packages/PyQt5/Qt5/plugins/platforms"
+export QT_QPA_PLATFORM="cocoa"
+export QT_MAC_WANTS_LAYER="1"
+
+# 启动应用
+python src/main.py
+```
+
+### 3. 使用虚拟环境专用安装
+```bash
+# 激活虚拟环境
+source .venv/bin/activate
+
+# 在虚拟环境中安装
+python fix_pyqt5_complete.py
+```
+
+## 环境变量说明
+
+| 变量名 | 作用 | 推荐值 |
+|--------|------|--------|
+| QT_PLUGIN_PATH | Qt插件主路径 | PyQt5/Qt5/plugins |
+| QT_QPA_PLATFORM_PLUGIN_PATH | 平台插件路径 | PyQt5/Qt5/plugins/platforms |
+| QT_QPA_PLATFORM | 指定平台 | cocoa (macOS) |
+| QT_MAC_WANTS_LAYER | macOS图层支持 | 1 |
+| QT_LOGGING_RULES | 日志级别 | qt.qpa.*=false |
+
+## 常见问题
+
+### Q: 为什么PyQt5会丢失平台插件？
+A: 常见原因：
+- 安装过程中断或失败
+- 虚拟环境迁移
+- 系统Qt库冲突
+- 文件权限问题
+
+### Q: 如何验证修复是否成功？
+A: 运行测试命令：
+```python
+python -c "from PyQt5.QtWidgets import QApplication; print('成功！')"
+```
+
+### Q: 修复后仍然有问题？
+A: 尝试：
+1. 完全删除虚拟环境重新创建
+2. 使用系统包管理器安装Qt5
+3. 检查Python版本兼容性
+
+## 最佳实践
+
+1. **始终使用虚拟环境**
+2. **固定PyQt5版本**（推荐5.15.10）
+3. **在代码中设置插件路径**
+4. **创建启动脚本**
+5. **定期验证安装**
+
+## 一键修复命令
+
+```bash
+# 完整的修复流程
+cd /Users/maziang/Documents/CodingWorkPlace/Code/Curriculum_Design
+python fix_pyqt5_complete.py
+source set_pyqt5_env.sh
+python src/main.py
+```
+
+这样应该能完全避免PyQt5平台插件问题！
