Install-Module is not making module importable on non-Windows systems #485
Description
Steps to reproduce
Install-Module FIFA2018
Import-Module FIFA2018Expected behavior
Module is imported into session. This is working fine on Windows machines (both Windows PowerShell or PowerShell Core). It is not working fine on Linux (error in next section).
Actual behavior
Import-Module : The specified module 'FIFA2018' was not loaded because
no valid module file was found in any module directory.
Initial investigation
Root cause for this behaviour seems to be case-sensitive search in Linux.
Module is having name with all capital letters FIFA2018 - both psm1 and psd1. However, it is getting saved to directory that has small letters fifa2018. Thus, Windows finds it, and Linux does not.
For this one module, problem can be resolved by renaming it in PS Gallery (how?).
I am more reporting inconsistency between PowerShellGet and built-in PowerShell commands. If Install-Module finds module with some name, it should save it with that exact name.
Interesting is that Get-InstalledModule will find it, but Get-Module -ListAvailable will not.
Check against PS Gallery
Aboput 4% of modules in PS Gallery would have similar problems. It is impacting even some high class modules like AzureRM.profile / AzureRM.Profile.
