Error Parsing Version string with nugetrepo

[sheldonhull]

    Humanizer                              = @{
        Name           = 'Humanizer'
        Source         = 'nugetrepo'
        DependencyType = 'Package'
        MinimumVersion = '3.11'
        Target         = 'C:\packages'
        DependsOn      = 'EnsureNugetRepositoryRegistered'
        Parameters     = @{
            ProviderName = 'nuget'
        }
    }

Using this statement to download a nuget package via nuget.exe provides an error that cannot convert double to version. This had been working until lately, so perhaps so version parsing method changed?

I'm currently using PSDepend version: 0.1.62

I just ran into this as well with a module from the PSGallery with just a major.minor version. Note that it only happens with the module has already been downloaded and PSDepend is doing a compare against the gallery. The issue stems from this code:

https://github.com/RamblingCookieMonster/PSDepend/blob/f514c3600546e4422c1a1d1c406254eb5f27a585/PSDepend/PSDependScripts/PSGalleryModule.ps1#L199

Running that line returns the following:

Find-Module -Name $Name -Repository $Repository | Measure-Object -Property Version -Maximum | Select-Object -ExpandProperty Maximum
0.3

This compared to what is returned with the existing module:

$Existing | Measure-Object -Property Version -Maximum | Select-Object -ExpandProperty Maximum
Major  Minor  Build  Revision
-----  -----  -----  --------
0      3      -1     -1

I'm wondering if the bug should be raised here or with PowerShellGet?

The only thing I can think of is to cast the output from Find-Module to System.Version. Not sure what that might break, though.

Just ran into this on a revived project:

This error happens when using psdepent 0.3.0. The below was workign until yesterday when MS pushed a new version of powershellget but the new version is 2.2 instead of being 2.2.0.
