Get-PSResource treats multiple paths set in the environment variable PSModulePath as a single path

[steveharsant]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.

Steps to reproduce

When executing Find-PSResource on PowerShell Core and 5.1 the $env:PSModulePath is treated as if it is a single path when it contains multiple paths for the different installation scopes.

For example:

PS /> Get-PSResource
Get-PSResource: Could not find a part of the path '/root/.local/share/powershell/Modules:/usr/local/share/powershell/Modules:/opt/microsoft/powershell/7/Modules'.

PS /> dir env:
Name                           Value
----                           -----
PSModulePath                   /root/.local/share/powershell/Modules:/usr/local/share/powershell/Modules:/opt/microsoft/powershell/7/Modules

The workaround is to set $env:PSModulePath with a single path and retry. For example:

PS /> $env:PSModulePath = '/root/.local/share/powershell/Modules'
PS /> Get-PSResource

Name          Version      Repository
----          -------      ----------
PowerShellGet 3.0.0-beta10 PSGallery

Expected behavior

PS /> Get-PSResource

Name          Version      Repository
----          -------      ----------
PowerShellGet 3.0.0-beta10 PSGallery

Actual behavior

PS /> Get-PSResource
Get-PSResource: Could not find a part of the path '/root/.local/share/powershell/Modules:/usr/local/share/powershell/Modules:/opt/microsoft/powershell/7/Modules'.

Thanks for bringing this to our attention @steveharsant, do you mean to say Get-PSResource in your title and description? We have marked it as a bug and will investigate further.
