Cannot Install-Module with pre-release module dependencies.

[peombwa]

I'm unable to install modules with prerelease dependencies despite me include -AllowPrerelease switch to Install-Module.

Steps to reproduce

ModuleA:

@{
    ModuleVersion     = '0.1.0'
    GUID              = '081f4c91-b4d8-441a-89e5-543859f68f2f'
    PrivateData       = @{
        PSData = @{
            Prerelease = 'preview1'
        }
    }
}

ModuleB:

@{
    ModuleVersion     = '0.1.0'
    GUID              = '4e54ce23-e81b-4e10-90a6-03a346085362'
    RequiredModules   = @('ModuleA')
    PrivateData       = @{
        PSData = @{
            Prerelease = 'preview1'
        }
    }
}

Both ModuleA and ModuleB are pre-release modules. ModuleB depends on ModuleA as specified in ModuleB's manifest.

• Pack both modules into nuget packges, then publish them to a repository of choice using nuget push.
• Run Install-Module -Name ModuleB -AllowPrerelease.

Sample Code.

Expected behavior

Pre-release versions of ModuleB and its dependency ModuleA should install successfully. Including -AllowPrerelease switch when executing Install-Module should also install pre-release versions (if any) of a module's dependency.

Actual behavior

I get an error message saying: Unable to find dependent module(s) (ModuleA)

Thanks for opening this issue, it is likely related to PowerShell/PowerShellGetv2#517 ...it would be helpful to know what module it is that you are trying to install? This issue will likely be fixed in the next release of PowerShellGet which we are targeting for the end of this year

@peombwa @SydneyhSmith We are seeing this same issue about unable to Install or Publish pre-release modules which depend on other pre-release modules. Is there any resolution to this? If not, what are the possible workarounds?
