python-3.x - 无法成功运行“func host start”来测试 azure 函数

问题描述

我正在尝试按照此处的 MSDN 说明对 python azure 函数进行一些本地测试： 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 并且我有一个有效的 Azure 订阅。我还通过az loginpowershell 管理员模式登录了我的 Azure 帐户。

一旦我完成了 MSDN 文档中的提示步骤并运行func host startpowershell 输出以下代码段。对我来说突出的错误是 AttributeError: module 'azure.functions_worker' has no attribute 'start_async'.我已经研究了这个错误并看到其他人通过巧克力卸载和重新安装 azure-functions-core-tools 成功解决了它，我按照这里的线程完成了：Azure Python App Function no本地运行时间更长 - 模块“azure.functions_worker”没有属性“start_async”

问题仍然存在，我无法在本地托管 azure 函数并在浏览器中测试 GET/POST 请求（http://localhost:7071/api/HttpTrigger）如果您熟悉如何解决此问题，请帮助我问题。我认为这可能是我的 Python 版本的问题，但我确认已通过python --version在 powershell 中运行安装了 Python 3.6.0

Now listening on: http://0.0.0.0:7071
Application started. Press Ctrl+C to shut down.

解决方案

我卸载了 Python 3.6.0，然后在虚拟环境中安装了 python 3.6.8。然后在解决问题的同一虚拟环境中卸载并重新安装 azure-functions-core-tools。通过 CMD 中的巧克力完成卸载和安装。我还暂时禁用了 Windows Defender 实时扫描。
