Troubleshooting

use_2to3 is invalid

error in PyBluez setup command: use_2to3 is invalid.

It looks like setuptools>=58 breaks support for use_2to3:

setuptools changelog for v58

So you should update setuptools to setuptools<58 or avoid using packages with use_2to3 in the setup parameters.

I was having the same problem, pip==19.3.1

또는 다음과 같이 setuptools 버전은 낮춘다. 

pip install "setuptools<58.0.0"
