        Install-Module posh-git -Force -Scope CurrentUser
    } catch {
        Write-Host "Failed to install posh-git module. Please install it manually using 'Install-Module posh-git'."
        return
    }

    $poshGitModule = Get-Module -Name posh-git
    if ($poshGitModule.Version -lt (Get-Module -ListAvailable -Name posh-git).Version) {
