function Install-PsGalleryModule { # .SYNOPSIS # Like install-Module but it manually installs the module when the normal way fails. # .DESCRIPTION # Installs a PowerShell module even on systems that don't have a working PowerShellGet. # But Sometimes you just need to apply a quick fix like this one: # # Unregister-PSRepository -Name PSGallery # Register-PSRepository -Default # if ((Get-PSRepository -Name PSGallery).InstallationPolicy -ne 'Trusted') { # Set-PSRepository -Name PSGallery -InstallationPolicy Trusted # } # When all that fails, then this function comes in handy.
