部署至Azure函数的FastAPI导入DefaultAzureCredential时触发ImportError问题求助

大家好，我碰到了个头疼的问题：我把一个FastAPI部署到Azure函数上，本地运行一切正常，但部署后只要导入DefaultAzureCredential就会报错，把那行导入代码删掉就能正常运行。

问题触发点 #

只要执行这行导入代码：

# 去掉这行程序就能正常运行
from azure.identity import DefaultAzureCredential 

立刻会抛出以下错误：

有没有大佬能帮忙分析下这个问题？本地跑完全没问题，一部署到Azure函数就出状况，实在摸不着头脑😭
