## 背景&操作步骤
> 做了什么操作后，出现的该问题
1. Error loading .py file. In source mode, check the file at [services/dataUpdate/service.py]. Error: No module named ‘pyodbc’
2. 需要手动在systemp环境安装才正常。在项目内requirements.txt添加pyodbc，没用。
c:\JitNode\system\bin\python\python.exe -m pip install pyodbc==5.2.0
3. 目前服务端还没升级，望官方测试后反馈 🤝
## 问题

#### 前端控制台错误截图 （如果只是后端问题，可跳过）

## 期望效果

我先了解下情况
旧桌面端之前有使用过sqlserver吗
Error: No module named ‘pyodbc’ 日志文件还在吗

直接在vs code中修改的 requirements.txt 打包插件缺陷，未打包，导致未自动安装依赖包
