The term 'Get-AzureRmPolicyDefinition' is not recognized as the name of a cmdlet, function, script file, or operable program

Question

I have problem with last task, assign policy:

Module AzureRM which contains Resources namespace (with Get-AzureRmPolicyDefinition) should be already included, right? https://github.com/Azure/azure-powershell/blob/preview/src/ResourceManager/Resources/Commands.Resources/help/Get-AzureRmPolicyDefinition.md

So why I have this error message?

The term 'Get-AzureRmPolicyDefinition' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

When I add to PowerShell task line:

Install-PackageProvider -Name NuGet -Force -Scope CurrentUser

Install-Module -Name Az.Accounts -RequiredVersion 1.6.2 -Force -Scope CurrentUser -AllowClobber

Install-Module -Name AzureRM.Resources -RequiredVersion 6.7.3 -Force -Scope CurrentUser -AllowClobber

Then I will at the end get:

Method 'get_SerializationSettings' in type 'Microsoft.Azure.Management.Internal.Resources.ResourceManagementClient' from assembly 'Microsoft.Azure.Commands.ResourceManager.Common, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation.

How to deal with that problem?

The warning in your log has display the issue caused:

Both Az and AzureRM modules were detected on this machine. Az and AzureRM modules cannot be imported in the same session or used in the same script or runbook. If you are running PowerShell in an environment you control you can use the 'Uninstall-AzureRm' cmdlet to remove all AzureRm modules from your machine....

Not sure what is your scripts in your previous tasks. But based on this error message, what I can sure is it installed the AzureRm module into the workspace. And as a result, AzureRM module has conflict with Az module in later steps.

Az module is the new module which we develope and used to replace the AzureRm module. But when you install the AzureRm and Az module into one workspace, it easily cause conflict which will lead the error.

There's no error on your scripts shared, so just need run Uninstall-AzureRm before your scripts to avoid this cmdlet conflicts.
