## 2026-04-15: 修复配置向导 500 错误
|
||
|
||
### 问题描述
|
||
添加集成时出现 500 Internal Server Error
|
||
|
||
### 根本原因
|
||
1. **类型注解错误**：`config_flow.py` 使用了小写 `any` 而非 `Any`
|
||
2. **依赖包不存在**：`manifest.json` 中引用了不存在的 `bleak-mesh>=0.2.0`
|
||
3. **导入错误**：`coordinator.py` 从错误的模块导入 `MeshMessageEvent` 和 `ProvDeviceEvent`
|
||
|
||
### 错误日志
|
||
|
||
#### 错误 1: 依赖包不存在
|
||
```
|
||
homeassistant.requirements.RequirementsNotFound:
|
||
Requirements for sigmesh_gateway not found: ['bleak-mesh>=0.2.0'].
|
||
```
|
||
|
||
#### 错误 2: 导入错误
|
||
```
|
||
Error occurred loading flow for integration sigmesh_gateway:
|
||
cannot import name 'MeshMessageEvent' from 'custom_components.sigmesh_gateway.protocol_parser'
|
||
```
|
||
|
||
### 解决方案
|
||
|
||
#### 修复 1: config_flow.py 类型注解
|
||
```diff
|
||
+ from typing import Any
|
||
|
||
- async def async_step_user(self, user_input: dict[str, any] | None = None) -> FlowResult:
|
||
+ async def async_step_user(self, user_input: dict[str, Any] | None = None) -> FlowResult:
|
||
```
|
||
|
||
#### 修复 2: manifest.json 依赖
|
||
```diff
|
||
- "requirements": ["pyserial-asyncio==0.6", "bleak-mesh>=0.2.0"],
|
||
+ "requirements": ["pyserial-asyncio-fast>=0.6"],
|
||
```
|
||
|
||
#### 修复 3: coordinator.py 导入
|
||
```diff
|
||
from .protocol_parser import (
|
||
DeviceManager,
|
||
DeviceState,
|
||
- MeshMessageEvent,
|
||
ParsedMeshMessage,
|
||
- ProvDeviceEvent,
|
||
ProtocolParser,
|
||
)
|
||
+ from .serial_reader import (
|
||
+ MeshMessageEvent,
|
||
+ ProvDeviceEvent,
|
||
+ SerialReader,
|
||
+ )
|
||
```
|
||

### 部署步骤
|
||
```bash
|
||
# 复制更新后的集成文件
|
||
cp -r /home/ubuntu/workspace/cherry-studio/enginneer/impress_sig_mesh_hacs/custom_components/sigmesh_gateway \
|
||
<HA 配置目录>/custom_components/
|
||
|
||
# 重启 Home Assistant
|
||
ha core restart
|
||
```
|
||
|
||
### 验证
|
||
重启后，在 HA UI 中重新尝试添加集成，应能正常显示配置表单。
