Aws lambda `sam本地调用`错误'；名称错误：名称'；NpipeHTTPAdapter'；未定义'；

我正在编写一个lambda函数，只是为了从AWS RDS表中获取一些数据。我能够成功运行

sam包

和

sam部署

，将功能部署到AWS

当我运行

sam build

时，它成功地构建，然后我运行

sam local invoke

在本地测试lambda，但我得到以下错误输出

$ sam local invoke

Docker Desktop也安装并运行在我的机器上。我已经打开并尝试通过MSI安装aws sam cli，但没有成功。我已经重新安装了Python、AWS CLI、AWS SAM CLI和Docker。我不知道下一步该去哪里

---

是否有任何修复程序可以让我的AWS Lambda函数在本地运行？

我最终需要卸载通过pip安装的sam cli版本，并改用Windows MSI安装程序。显然，使用MSI是Windows所需的安装方法。然后使用“sam.cmd”调用sam cli

我认为你的情况与这里描述的类似：tl；dr-尝试通过Windows.msi而不是pip.Yup安装SAM CLI这是我的问题。谢谢你的回复！当我遇到这个问题时，我正在使用.msi，所以我删除并重新安装了它。对我来说，问题是我安装了旧版本的CLI。我还安装了几个旧版本的Python，但没有用。删除所有python，然后删除并重新安装SAM CLI。
