通过pip安装毕色和导入的麻烦

Question

我必须使用毕达斯特（Pybluez）做某事，我的代码上有错误，所以我告诉自己要以“代码示例”毕毕尔布鲁斯（Pybluez）中的内容开始，但是我也有示例中的错误。

这是一个例子：

#!/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.")

所以我试图通过PIP重新安装毕色，我卸载了它并运行了命令

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

我也有错误...

我很困惑，因为这是导入错误，在大多数情况下，您只需要重新安装模块...

Answer 1

毕色库图书馆的问题是问题，当我将每个“蓝牙”更改为“插座”时，它可以正常工作。

Answer 2

为什么不安装轮套？
在我的Windows 10 CMD中，它起作用了。
