Ich kann nicht meine schreiben in Dateicode die Fehlermeldung funktioniert writeFile kann nicht gelöst werden. Ich versuche die Board-Positionen in eine Textdatei zu schreiben, damit das Spiel gespeichert werden kann. Wenn der Benutzer das Spiel speichern möchte, sollte er ein neues Unterprogramm aufrufen, das die Teile in die Datei schreibt.Ich kann nicht den Schreibvorgang in Datei-Teil des Codes zu arbeiten
