我正在尝试在Windows上安装azure IoT Edge运行时。我正在关注Install and start the IoT Edge runtime上的Microsoft文档。文档告诉您如何在Powershell中运行命令。我想将以下命令的输出保存到变量中，以便可以检查天气安装是否成功
. {Invoke-WebRequest -useb aka.ms/iotedge-win} | Invoke-Expression; `Deploy-IoTEdge -ContainerOs Windows
我已经尝试过这里介绍的几种解决方案
How do I capture the output into a variable from an external process in PowerShell?
How to capture output in a variable rather than a logfile?
修改
作为上述命令的输出，我的错误越来越小
