通過 pip 安裝 PyBluez 並遇到導入問題

Question

我必須使用 Pybluez 做一些事情，我的代碼有錯誤，所以我告訴自己從 Pybluez 中的“代碼示例”開始，但我在示例中也有錯誤。

這是例子：

#!/usr/bin/env python3
import bluetooth

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

port = server_sock.getsockname()[1]

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

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

print("Waiting for connection on RFCOMM channel", port)

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

try:
    while True:
        data = client_sock.recv(1024)
        if not data:
            break
        print("Received", data)
except OSError:
    pass

print("Disconnected.")

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

所以我嘗試通過 pip 重新安裝 Pybluez，我卸載了它並運行了命令

pip install git+https://github.com/pybluez/pybluez#egg=Pybluez

我也有錯誤...

我很困惑，因為它是導入錯誤，在大多數情況下你必須重新安裝模塊......

Answer 1

這是 Pybluez 庫的問題，當我將每個“藍牙”更改為“套接字”時，它可以正常工作。

你為什么不安裝輪子 package？ 在我的 windows 10 cmd 中，它起作用了。
