Question

我的功能运行了一段时间但突然间什么都没有了。我按照https://prmadi.com/running-python-code-on-azure-functions-app/中的说明成功完成了操作。代码是从Github自动部署的。然而，几周前出了问题。我还没有解决我的问题，但我已经想出了一些事情：

1）我安装的模块（使用pip）已经消失或无法再找到。我设法安装它们，但它们会在几个小时内消失。

2）该功能运行2.7。我想这是因为PATH已经改变了。以前\ home \ site \ tools就在路径中。这已不再是这种情况。之前的工作是使用nuget site-extension安装python 3，然后将其移动到\ home \ site \ tools文件夹。我试图将python3安装移到例如路径中的/ home / site / deployments / tools。

更新：我尝试使用此处的说明：https://lnx.azurewebsites.net/python-3-6-deployments-on-azure-function-apps/。我设法让我的函数运行python 3，我设法让Azure安装所需的模块。所以简而言之，我有以下文件夹结构：

requirements.txt
├── function
    ├── deploy.cmd
    ├── .deployment
    ├── function.json
    ├── run.py

这实际上有效，但过了一段时间我要么1）回到python 2.7并没有包或我收到错误信息

尽管如此我可以打开控制台并运行代码而不会出错。所以我尝试重新部署该功能，但没有运气。我想azure会在某些时间间隔运行一些清理工作？

最佳

Answer 1

问题解决了。它是由Azure https://github.com/Azure/azure-webjobs-sdk-script/issues/1758

中的错误引起的

基本上只需在＆＃34;功能应用设置＆＃34;中回滚到旧版本（例如1.0.11296）一切都有效:-)

python3不再适用于Azure功能
