Import-Module PnP.PowerShell Error - Could not load file or assembly System.Management.Automation

Recently I was working on custom development. I needed to run an PowerShell Command and when I tried to run that command, I didn’t find basic commands like Register-PnPManagementShellAccess” or “Connect-PnPOnline” commands. So, I uninstall everything and reinstall. But still I was getting below error:

Error:

Import-Module : Could not load file or assembly 'System.Management.Automation, Version=7.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.




Then I thought it might be helpful if I switch to Windows PowerShell ISE to debug what is happening. And it showed me more details like the commands I was searching for were not included in the module.




Solution:

After some digging, I found out that with this issue happened with the newer version PnP PowerShell 2.1.1. We need to forcefully install 1.12.0 version.

• Uninstall all versions and then install correct 1.12.0 version. Use below command to remove all the version:

 Uninstall-Module PNP.PowerShell -AllVersions  

• Set Tls12 protocol with below command

 [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12  

• Install NuGet using below command

 Install-PackageProvider -Name nuget -MinimumVersion 2.8.5.201 -force  

• Install PnP.PowerShell with version 1.12.0 using below command

  Install-Module -Name "PnP.PowerShell" -RequiredVersion 1.12.0 -Force –AllowClobber
