We have two PowerShell editions what we could use on Windows, these are Windows PowerShell and PowerShell (Core). Now one of the challenges we face with the two editions comes from where they store the installed PowerShell modules. Depending on the folder, it's possible that we need to install a module twice and that means we'll need to keep both versions up-to-date independently from each other. But there is a solution for this challenge!
Quick look at $env:PSModulePath
PowerShell (both editions) uses the PSModulePath environment variable
$env:PSModulePath to store the list of folders which could be used to store PowerShell modules.
Note: It is possible to extend the list of folders by editing the user or system level environment variable.
Let's compare the two lists:
Note: It is expected that the list of folders will not be the same on every computer. But there are some default folders on this list.
|C:\Program Files\WindowsPowerShell\Modules||C:\Program Files\WindowsPowerShell\Modules|
|C:\Program Files\Microsoft Monitoring Agent\Agent\PowerShell\||C:\Program Files\Microsoft Monitoring Agent\Agent\PowerShell\|
|C:\Program Files\Microsoft Monitoring Agent\Agent\AzureAutomation\7.3.1125.0||C:\Program Files\Microsoft Monitoring Agent\Agent\AzureAutomation\7.3.1125.0|
As you can see
C:\Program Files\WindowsPowerShell\Modules is being used by both PowerShell editions, which means those modules which support both PowerShell editions could be placed - or installed - into this folder, and they will be visible for both editions. And we only need to keep these modules updated once. \o/
How to install modules into this folder?
The easiest way (if you ask me, and I'm writing this post which means I asked me) is running Windows PowerShell as an admin and execute
Install-Module without using the
-Scope parameter. For example:
Install-Module Microsoft.PowerShell.SecretManagement, Microsoft.PowerShell.SecretStore
That's it. Happy scripting!
