python3不再适用于Azure函数

我的功能已经运行了一段时间，但突然间什么都不起作用了。我成功地遵循了这里的指示。代码是从Github自动部署的。然而，几周前事情出了问题。我没有解决我的问题，但我已经解决了一些问题：

1） 我安装的模块（使用pip）已丢失或无法再找到。我设法安装了它们，但几个小时后它们就消失了

2） 该函数运行于2.7版。我想这是因为道路已经改变了。以前的\home\site\tools位于路径中。情况不再如此。以前的工作是使用nuget site extension安装python 3，然后将其移动到\home\site\tools文件夹。我已尝试将python3安装移动到路径中的/home/site/deployments/tools

更新：我尝试使用以下说明：。我设法让我的函数运行Python3，并设法让Azure安装所需的模块。因此，简而言之，我有以下文件夹结构：

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

部署是

这实际上是可行的，但过了一段时间，我要么回到python 2.7，没有包，要么收到错误消息

尽管如此，我可以打开一个控制台，运行代码而不会出错。因此，我尝试重新部署该函数，但没有成功。我猜azure会每隔一段时间进行一些清理或其他工作

最好解决问题。这是由Azure中的一个bug引起的

基本上，只需在“功能应用程序设置”中回滚到旧版本（如1.0.11296），所有功能都会恢复正常：-）

您好，请发布更多关于您的代码的详细信息，让我为您服务好吗？您好，Jay Gong。我试图添加更多细节：-）
