little sexy script I made to stop having fnm (Fast Node Manager - https://github.com/Schniz/fnm) from not being detected by the Path on PowerShell - just reinstalls it! You can do this same kinda thing with anything! This script is part of my $PROFILE

Microsoft.PowerShell_profile.ps1

function Test-Fnm {
    if (-not (Get-Command fnm -ErrorAction SilentlyContinue)) {
        $flagFile = "$env:TEMP\fnm_installing.flag"
        if (-not (Test-Path $flagFile)) {
            New-Item -Path $flagFile -ItemType File | Out-Null
            try {
                Start-Process powershell -ArgumentList "-NoProfile -Command `"winget install Schniz.fnm; Remove-Item -Path $flagFile`"" -WindowStyle Hidden
                $maxRetries = 12  # wait up to 60 seconds (12 * 5)
                $retry = 0
                while (-not (Get-Command fnm -ErrorAction SilentlyContinue) -and $retry -lt $maxRetries) {
                    Start-Sleep -Seconds 5
                    $retry++
                }
            }
            catch {
                Remove-Item -Path $flagFile -ErrorAction SilentlyContinue
            }
        }
    }
}

if (Get-Command fnm -ErrorAction SilentlyContinue) {
    fnm env --use-on-cd | Out-String | Invoke-Expression

else {
    Write-Host "fnm installation did not complete successfully."
