PowerShell x64 无法识别 Install-Module 无法识别为 cmdlet 的名称

Question

I know Install-Module is a PowerShell 5 or above feature.

I am running Windows 10 pro version 20H2 with OS-build:19042.746

I checked the version of PS using $PSVersionTable . The output is provided below.

PS C:\Windows\system32> $PSVersionTable

Name                           Value
----                           -----
PSVersion                      5.1.19041.610
PSEdition                      Desktop
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0...}
BuildVersion                   10.0.19041.610
CLRVersion                     4.0.30319.42000
WSManStackVersion              3.0
PSRemotingProtocolVersion      2.3
SerializationVersion           1.1.0.1

Another thing that I found out while searching for the fix is that, The PowerShell x86 version is working fine and there are no issues.

I can't run the Window Management Framework 5.1 because it was meant for other systems to upgrade the PowerShell. However, I am running the latest version.

Is there any fix for 64bit?

Answer 1

A workaround I found is copying the Modules folder in Program Files (x86)\WindowsPowershell to Program Files\WindowsPowershell (64 bit folder). Somehow the modules got deleted from the 64 bit Powershell folder. I cannot pinpoint the exact reason but I suspect the culprit may be the KB5001330 update.

Answer 2

Huh, I wonder if this is a bug?

The PowerShell x86 version is working fine and there are no issues.

This comment doesn't make sense as Install-Module is part of the PowerShellGet module, which shouldn't care if you're running the x64 or x86 shell. Regardless, here's a few things you can try.

• You could manually download PowerShellGet ( PackageManagement is a dependancy). Related:

# check if PowerShellGet is available locally
Get-Module PowerShellGet -List

# check if PackageManagement is available locally
Get-Module PackageManagement -List

• Have you ran Windows Update? If not: run it, restart, repeat until there's nothing left.
• .NET should have been installed with the operating system - check if it was.

# Needs to be run in an Admin shell. Alternatively, us the gui in next point
Get-WindowsOptionalFeature -Online -FeatureName NetFx* | Format-Table

# if not, you can add it by going typing 'windows feature' in the start menu and going to
# 'Turn Windows feature on or off'

I don't know if it was a bug or not. I just reinstalled the windows and problem got fixed.
