Firefoxが問題のあるセレン - アップデートにもかかわらずFirefoxが応答しない

Question

Seleniumを使用してブラウザ（Firefox）を開く機能テストを実行しようとすると、わかりにくいという奇妙なメッセージが表示されます。私は既にpip install -upgrade seleniumを使ってSeleniumを更新しただけでなく、最新のFirefoxを再インストールしましたが、それは役に立たなかった。ここに私のエラーメッセージの全文があります。助言がありますか？

あなたがFirefoxDriverを使用していては、Firefox 47がインストールされている場合、Mozillaはマリオネットにスイッチングしているので、あなたが代わりにMarionetteDriverを使用してになります。
