【问题描述】：

我正在尝试使用 Azure Devops 构建一个 Flask 应用程序，我点击了这个链接

https://docs.microsoft.com/en-us/azure/devops/pipelines/ecosystems/python-webapp?view=azure-devops

我能够成功构建和部署示例应用程序。

但是当我在 requirements.txt 中添加其他包并将其推送到 Azure 存储库时。 .yaml 文件自动运行，但在构建阶段，所有包都在安装，在管道阶段和部署阶段我没有收到任何错误，但是当我尝试测试应用程序时，它显示包未找到错误。我没有更改 .yaml 文件中的任何内容

【解决方案1】：

看到他们激活了虚拟环境的帖子 - 确保检查您安装的包是否确实在您的 VENV 中，并将 WEBSITE_RUN_FROM_PACKAGE = 1 添加到网络应用程序！

Reference Post

当 Python 函数应用无法加载 Python 模块时会出现此问题。这可以扩展到您的场景

找不到包
无法使用适当的 Linux 轮解析软件包
包与 Python 解释器版本不兼容
包与其他包冲突
该软件包仅支持 Windows 或 macOS 平台（您可以放心地忽略此选项）
