Unable to install PyBluez in windows 10 on python 3.8

Question

When I try to install PyBluez on my PC, it displays to an error as shown below. I have installed a C++ compiler. I don't know what the problem is and how to fix it. I even tried to download a zip from their Github and then tried to install I used pip setup.py install it installed, but I wasn't able to import the bluetooth library. Can anyone help?

  Using cached PyBluez-0.23.tar.gz (97 kB)
Using legacy 'setup.py install' for pybluez, since package 'wheel' is not installed.

Answer 1

This may be too late, but I faced the same issue. I will provide below two directions for you to take to make PyBluez work. This is more of a workaround, since I was not able to resolve all PyBluez issues on my own system using Python 3.9.x. In both cases you are required to change python version. You can pick what works for you and your needs.

ALTERNATIVE 1: Using Python 3.9.x Sockets

Out of the box, Python 3.9.x can connect to Bluetooth using sockets.

import socket
sock = socket.socket(socket.AF_BLUETOOTH, socket.SOCK_STREAM, socket.BTPROTO_RFCOMM)
sock.connect((host, port))

ALTERNATIVE 2: Use Python 3.7.x with pyenv and pipenv

1. Dependencies (also ensure your paths are set properly)

• pipenv
• pyenv-win

2. Check the latest version of Python 3.7 available. Most likely will be 3.7.7.

pyenv install --list

3. Install python using pyenv

pyenv install 3.7.7

4. Go to your project's folder and create a virtual environment using the python version installed

pipenv --python 3.7.7

5. Clone and Build Pybluez from source

git clone https://github.com/pybluez/pybluez.git 
cd pybluez/
python setup.py build

6. Install PyBluez within your virtual environment

pipenv shell
python setup.py install

From there, you should be able run any projects within this virtual environment using python 3.7.7, which is able to properly build and install PyBluez. I have not found any other methods of making PyBluez install as of now.

Answer 2

只需安装正确的版本 pip install pybluez2
