Azure App Server中的烧瓶
问题描述：
你好
我正在尝试在Azure App Server上部署Flask项目.我遵循了官方指南，该指南在使用样品瓶项目时成功运行.
I am trying to deploy a flask project on Azure App Server. I have followed the official guide which worked successfully when using a sample flask project.
我有我自己的flask项目，该项目可以在计算机上本地完美运行.当我尝试在Azure上部署它时，我收到以下错误日志.我认为这可能与Azure Linux服务器和库的可用性有关.
I have my own flask project, which runs perfectly locally on my computer. When I try to deploy it on Azure, I get the following following error log. I believe this may have to do with the Azure Linux Server and the library availability.
