当我尝试在PC上安装PyBluez时，它显示如下错误。我已经安装了C ++编译器。我不知道问题是什么以及如何解决。我什至尝试从他们的Github下载一个zip文件，然后尝试使用pip setup.py install安装它，但是我无法导入蓝牙库。有人可以帮忙吗？

这可能为时已晚，但我遇到了同样的问题。我将提供以下两个方向供您使用，以使 PyBluez 工作。这更像是一种解决方法，因为我无法使用 Python 3.9.x 在自己的系统上解决所有 PyBluez 问题。在这两种情况下，您都需要更改 python 版本。您可以选择适合您和您的需求的方法。
开箱即用，Python 3.9.x 可以使用套接字连接到蓝牙。
import socket
sock = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_STREAM, socket.BTPROTO_RFCOMM)
sock.connect((host, port))
1.依赖项（还要确保您的路径设置正确）
2.检查可用的 Python 3.7 的最新版本。最有可能是 3.7.7。
pyenv install --list
3.使用pyenv安装python
pyenv install 3.7.7
4.转到您项目的文件夹并使用安装的 python 版本创建一个虚拟环境
pipenv --python 3.7.7
5.从源代码克隆和构建 Pybluez
git clone https://github.com/pybluez/pybluez.git
cd pybluez/
python setup.py build
6.在您的虚拟环境中安装 PyBluez
pipenv shell
python setup.py install
从那里，您应该能够使用 python 3.7.7 在这个虚拟环境中运行任何项目，它能够正确构建和安装 PyBluez。到目前为止，我还没有找到任何其他安装 PyBluez 的方法。
