Python："AttributeError:模块' lightblue‘没有属性’查找设备‘“

Question

。

大家好，希望你们做得好！

我正在尝试编写一个Python (3.8.9)脚本，这样我的计算机就可以检测到它能找到的每一个蓝牙设备，并向我提供它找到的设备列表。然后，我安装了pybluez和lightblue

pip3安装pybluez

和

pip3安装python

python-lightblue的版本为1.0.3。下面是我的代码：

import bluetooth

def scan():
    print("Scanning for bluetooth devices:")
    devices = bluetooth.discover_devices(lookup_names = True, lookup_class = True)
    number_of_devices = len(devices)
    print(number_of_devices," devices found")
    for addr, name, device_class in devices:
        print("\n")
        print("Device:")
        print("Device Name: %s" % (name))

当我运行这个程序时，我会发现以下错误：

Traceback (most recent call last):
  File "bluetooth_detect.py", line 16, in <module>
    scan()
  File "bluetooth_detect.py", line 5, in scan
    devices = bluetooth.discover_devices(lookup_names = True, lookup_class = True)
  File "/Users/<my_name>/Library/Python/3.8/lib/python/site-packages/bluetooth/macos.py", line 12, in discover_devices
    devices = lightblue.finddevices(getnames=lookup_names, length=duration)
AttributeError: module 'lightblue' has no attribute 'finddevices'

然而，当我查看互联网上的文档时，模块lightblue确实有属性finddevices，而且我在另一个论坛上找不到任何提到这个问题的地方(也许我查找的时间不够长?)

有人知道吗？先谢谢各位：)

我认为问题是在三年前的最新版本的pip注册。尝试从GitHub从主服务器安装

pip安装git+https://github.com/pybluez/pybluez.git

这将解决你的问题
