我在Windows Server 2012 R2构建服务器上安装了64位专用代理。我已将此连接到Azure Dev Ops。在生成服务器上，我仅安装了5.6.0版的AzureRM，因为这是我要运行的脚本所必需的。如果您有兴趣，请参阅我的其他问题：How to set PITR for all databases in a Azure Sql Database Elastic Pool?
如果我在Azure DevOps中创建Azure PowerShell v3任务以运行以下内联脚本：
Get-Module -Name AzureRM* -ListAvailable
我收到此错误：

如果我以构建服务器帐户登录到构建服务器并打开PowerShell窗口，则可以正常运行。在Azure DevOps中的常规PowerShell任务中，它也可以正常工作。
我的PowerShell脚本需要在Azure帐户的上下文中运行，如何实现？
编辑
我已经尝试过Azure PowerShell任务v1和v2，但没有用。我还尝试在版本选项部分中将PowerShell版本指定为5.6版本，以及最新安装的版本。这些都不起作用。
