【Azure 应用服务】Python3.7项目在引用pandas 模块后，部署报错

问题描述

参考“快速入门：在 Linux 上的 Azure 应用服务中创建 Python 应用” 文档，在App Service For Linux环境中部署Python应用，在添加了pandas，应用本地运行成功，但是部署到App Service后，启动报错：Application Error

问题分析

获取日志：

可以通过高级工具（kudu）连接到App Service后台，因为是Linux系统，所以通过SSH或者Bash都可以查看网站的部署文件及日志(LogFiles文件夹)。针对在启动时候就出现错误，另一种有效的方式是查看日志流：

其中的原因就是因为没有成功加载pandas模块，所以应用启动失败。而在Linux的环境中，是因为在部署时候，缺少了antenv.tar.gz文件包。
