带pip问题的Gattlib安装

Question

最近，我一直在尝试使用pip将gattlib安装到python中，如下所示：

sudo -H python -m pip install gattlib

但结果就是这个错误：

Collecting gattlib

Building wheels for collected packages: gattlib

  ERROR: Failed building wheel for gattlib

我的目标是使用我的PC机的内置BLE模块，通过pybluez库通过python进行通信。我使用的是Python的旧版本，因为我想要使用它的脚本是用Python 2.7编写的。到目前为止，我能够使用以下命令在Python 3.8中安装gattlib库：

sudo -H python3 -m pip install gattlib

我已经在Python2.7和Python3.8中安装了pybluez库，当我用耳机测试它时，它似乎可以工作。另外，gattlib库似乎在python3.8中工作，因为我能够用它检测ESP32 BLE服务器，但在python2.7中它不工作，因为gattlib库丢失了。 Python3.8在尝试使用BLE时也需要sudo权限，您知道如何避免这种情况吗

测试时，我使用了以下pybluez测试示例：

# simple inquiry example
import bluetooth

nearby_devices = bluetooth.discover_devices(lookup_names=True)
print("Found {} devices.".format(len(nearby_devices)))

for addr, name in nearby_devices:
    print("  {} - {}".format(addr, name))

BLE：

# bluetooth low energy scan
from bluetooth.ble import DiscoveryService

service = DiscoveryService()
devices = service.discover(2)

for address, name in devices.items():
    print("name: {}, address: {}".format(name, address))

你知道如何解决安装错误吗？ 提前谢谢
