RPi 3 Python Script - NameError：name 'BluetoothSocket'が定義されていません

Question

これはPythonスクリプティングには比較的新しいので、ラズベリーとスマートデバイスの間でBluetooth経由で無線LANを設定することになっています。残念ながら、私はタイトルに記載されているエラーを実行し続けます。誰かがコードをコピーして実行し、私がこのエラーに遭遇し続ける理由を教えてくれることを願っていました。すべての助けが大変ありがとう！

は、このコードの出力

あなたは私達にあなたのpythonのバージョンを表示することができますか？

ジャストタイプ：

$ python --version 

bluetooth libに存在しているようです。しかしないBluetoothSocket：これにかなり新しいもの@クリスのためのbluezとのpython-のbluez

$ sudo apt-get install bluez 
$ sudo apt-get install python-bluez
