Info nicht abgeschlossen ist, welchen Browser Sie verwenden. Wenn Sie ChromeDriver verwenden, aktualisieren Sie Ihren Chrome-Browser und laden Sie die neueste Version von Chrome Driver über diesen Link http://chromedriver.storage.googleapis.com/index.html. und benutze wait, dann benutze es. Wenn Sie Firefox verwenden, lassen Sie es mich wissen.
