python藍牙錯誤-沒有名為_bluetooth的模塊

Question

我正在嘗試作為藍牙服務器的python中的示例代碼。 此代碼給出以下錯誤。

追溯（最近一次通話）：文件“ / var / lib / cloud9 / examples / Sa / rfcomm-server_py”，第7行，從藍牙導入*文件“ / var / lib / cloud9 / examples / Sa / bluetooth / init “ .py”，第43行，來自.bluez import *文件“ /var/lib/cloud9/examples/Sa/bluetooth/bluez.py”，第6行，作為_bt ImportError導入_bluetooth：沒有名為_bluetooth的模塊

我在cloud9 IDE中使用beaglebone綠色無線板

   from bluetooth import *

   server_sock=BluetoothSocket( RFCOMM )
   server_sock.bind(("",PORT_ANY))
   server_sock.listen(1)

   port = server_sock.getsockname()[1]

   uuid = "94f39d29-7d6d-437d-973b-fba39e49d4ee"

   advertise_service( server_sock, "SampleServer",
               service_id = uuid,
               service_classes = [ uuid, SERIAL_PORT_CLASS ],
               profiles = [ SERIAL_PORT_PROFILE ], 
 #                   protocols = [ OBEX_UUID ] 
                )

  print("Waiting for connection on RFCOMM channel %d" % port)

  client_sock, client_info = server_sock.accept()
  print("Accepted connection from ", client_info)

 try:
 while True:
    data = client_sock.recv(1024)
    if len(data) == 0: break
    print("received [%s]" % data)
 except IOError:
  pass

  print("disconnected")

 client_sock.close()
  server_sock.close()
   print("all done")

我沒有在Beaglebone綠色無線板上打開藍牙，但是在運行以下命令后，上面的代碼運行良好：

$ bb-wl18xx-bluetooth
