无法成功运行'func host start‘来测试azure功能

Question

我正在尝试按照这里的MSDN指令执行一些python azure函数的本地测试：https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-first-function-python

我已经安装了所有必要的依赖项，包括Python 3.6、Azure Functions Core Tools、Azure CLI &我有一个活动的Azure订阅。我还在powershell管理员模式下通过az login登录了我的Azure帐户。

一旦我完成了MSDN doc & run func host start powershell中提示的步骤，就会输出以下代码片段。我发现的一个错误是核心工具。我研究过这个错误，并看到其他人通过巧克力卸载并重新安装azure- AttributeError: module 'azure.functions_worker' has no attribute 'start_async'. - Azure Python App Function no longer runs locally - module 'azure.functions_worker' has no attribute 'start_async'成功地解决了这个问题。

问题仍然存在&我无法在本地托管azure函数&在浏览器(http://localhost:7071/api/HttpTrigger)中测试GET/POST请求。如果您熟悉如何解决此问题，请帮助我。我认为这可能是我的Python版本的问题，但我通过在powershell中运行python --version确认安装了Python3.6.0

我卸载了Python 3.6.0，然后在一个虚拟环境中安装了python 3.6.8。然后卸载并重新安装azure-functions-core-tools在同一个虚拟环境中，解决了这个问题。卸载&在CMD中通过巧克力完成安装。我还暂时禁用了Windows Defender实时扫描。
