While installing/upgrading Azure PowerShell az module I faced below error. I was using Powershell Desktop Version 5.1 and it by default comes with Windows 10 OS. I cannot install PowerShell Core (another application) due to restrictions. So thought of using whatever I have on my received laptop.
Install-Module az -Force PackageManagement\Install-Package : Cannot convert value "2.0.0-preview" to type "System.Version". Error: "Input string was no in a correct format." At C:\Program Files\WindowsPowerShell\Modules\PowershellGet\1.0.0.1\PSModule.psm1:1890 char:21 + ... $null = PackageManagement\Install-Package @PSBoundParameters + + CategoryInfo : InvalidArgument: (Microsoft.Power....InstallPacakage:InstallPackage) [Install-Package], Exception + FullyQualifiedErrorId : InvalidCastParseTargetInvocation,New-PSGetItemInfo,Microsoft.PowerShell.PackageManagement.Cmdlets.InstallPackage
Whenever you install any module from PowerShell repository it uses PowershellGet and PackageManagement modules to get task done in the background and it auto loaded module when required. Once I verify listing modules with below commands, It shows me the version 1.0.0.1 is very initial one for PowershellGet. After finding related modules from internet psgallery repository. I see latest version available online versions are PowershellGet 2.2.3 and PackageManagement 1.4.6. (This requires Admin Access).
Get-Module -ListAvailable PowershellGet, PackageManagement
Find-Module PowershellGet -IncludeDependencies
In next instructions install latest versions.
Next install PowershellGet module, it will install latest version and dependent module PackageManagement as shown in the below commands. You cannot completely uninstall initial version of module using (Uninstall-Module). but they can co-exist with each other. What can be done is we can stop using older version with Remove-Module PackageManagement, PowershellGet -Force to unload it.
Install-Module PowershellGet -Force
Get-Module PackageManagement, PowerShellGet
Get-Module PackageManagement, PowerShellGet -ListAvailable
To verify use with and without -ListAvailable parameter using Get-Module to compare which modules are available and loaded.
In the last try installing az module, I am using it to install to logged in Current User profile only, Once az module is downloaded, it is not auto loaded until you use Az related comdlets/functions/scripts, to get list use -ListAvailable parameter using Get-Module command.
Install-Module az -Scope CurrentUser
Get-Module az
Get-Module -ListAvailable
