What is Install-Module command in Powershell?

powershell

Various Microsoft articles refer to the Powershell command Install-Module, but I can't find any reference to what this actually is and it's not very amenable to googling. I have psget installed, so I have its version of Install-Module ... but I think that's not the Install-Module that everyone else is talking about.

Ah, I found this Install-Module. Is that a different one to the one that PsGet installs? If so should I uninstall PsGet so I get back to the default one?

Solution 1:

I had previously installed PSGet which had overwritten my version of Install-Module. You can check this by running help install-module and see which version it refers to.

I couldn't find uninstall documentation for PSGet so I removed it by deleting the folder C:\Users\Rory\Documents\WindowsPowerShell\Modules\PSGet. Now help install-module refers to the microsoft version.

Solution 2:

You can work around the clash by prefixing the command with the module name:

PsGet installed and getting in the way:

C:\repos> install-module csproj
Module csproj was not found in central repository
At C:\Users\Administrator\Documents\WindowsPowerShell\Modules\PsGet\PsGet.psm1:694 char:13
+             throw "Module $Module was not found in central repository ...
+             ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OperationStopped: (Module csproj w...tral repository:String) [], RuntimeException
    + FullyQualifiedErrorId : Module csproj was not found in central repository

using the qualified name:

C:\repos> powershellget\install-module csproj

Untrusted repository
You are installing the modules from an untrusted repository. If you trust this repository, change its InstallationPolicy value by running
the Set-PSRepository cmdlet. Are you sure you want to install the modules from 'PSGallery'?
