Error: unhandled exception: paramCount is not implemented on Nintendo Switch [OSError]

[lotzz]

I got this error msg from this code
    
    
    #The file is get_saves.nims
    
    import parseopt
    import "check_installed.nims"
    echo check_installed.exists
    var ops = initOptParser()
    while true:
      ops.next
      case ops.kind
      of cmdEnd: break
      of cmdLongOption, cmdShortOption:
        echo "got and option"
      of cmdArgument:
        echo "got and argument"
    
    
    Run

Here is the other file "check_installed.nims"
    
    
    from os import `/`
    mode = ScriptMode.Verbose
    
    var user_profile = getEnv("userprofile")
    let minecraftDir = user_profile / "AppData/Roaming/.minecraft"
    var exists* = false
    if dirExists(minecraftDir):
      exists = true
      echo "The Java Edition of minecraft has been installed on this system"
      echo "We will now be creating a directory: .resourceManager in your 
UserProfile directory( " & user_profile & " )"
    else:
      echo "The Java Edition of minecraft has not been installed on this system"
      echo "Exiting..."
      quit(0)
    
    
    Run

This might be a little spammy, but I am just trying to make a simple script 
that checks if minecraft is installed, grabs my save folder and allows me to 
manage resource packs and datapacks from another area using a CLI.

This is the output I get from running "nim get_saves.nims"

I am on a Windows 10 OS and i wonder if this is some kind of bug
