<# .SYNOPSIS Installs a module from a PowerShell repository like the PowerShell Gallery using nuget.exe .DESCRIPTION Installs a module from a PowerShell repository like the PowerShell Gallery using nuget.exe Note: If we find an existing module that doesn't meet the specified criteria in the Target, we remove it. Relevant Dependency metadata: Name: The name for this module Version: Used to identify existing installs meeting this criteria, and as RequiredVersion for installation. Defaults to 'latest' Source: Source Uri for Nuget. Defaults to https://www.powershellgallery.com/api/v2/ Target: Required path to save this module. No Default Example: To install PSDeploy to C:\temp\PSDeploy, I would specify C:\temp AddToPath: Prepend the Target to ENV:PSModulePath .PARAMETER Force If specified and Target already exists, remove existing item before saving .PARAMETER Import If specified, import the module in the global scope .PARAMETER PSDependAction Test, Install, or Import the module. Defaults to Install Test: Return true or false on whether the dependency is in place Install: Install the dependency Import: Import the dependency .EXAMPLE @{ PSDeploy = @{ DependencyType = 'PSGalleryNuget' Target = 'C:\Temp' Version = '0.1.19' } } # Install PSDeploy via nuget PSGallery feed, to C:\temp, at version 0.1.19 .EXAMPLE @{ PSDeploy = @{ DependencyType = 'PSGalleryNuget' Source = 'https://nuget.int.feed/' Target = 'C:\Temp' } } # Install the latest version of PSDeploy on an internal nuget feed, to C:\temp, #> [cmdletbinding()] param( [PSTypeName('PSDepend.Dependency')] [psobject[]]$Dependency, [switch]$Force, [switch]$Import, [ValidateSet('Test', 'Install', 'Import')] [string[]]$PSDependAction = @('Install') ) # Extract data from Dependency $DependencyName = $Dependency.DependencyName $Name = $Dependency.Name if(-not $Name) { $Name = $DependencyName } $Version = $Dependency.Version if(-not $Version) { $Version = 'latest' } $Source = $Dependency.Source if(-not $Dependency.Source) { $Source = 'https://www.powershellgallery.com/api/v2/' } # We use target as a proxy for Scope $Target = $Dependency.Target if(-not $Dependency.Target) { Write-Error "PSGalleryNuget requires a Dependency Target.
