Black requires Python 3.6+ and you may want to look at pre-commit as it is capable of creating a python3 virtual environment just for black.

pip3 install --user black[python2]

With python2 option black will check py2 code correctly, but for running black you need py3

Did you try?

pip install black

Black can be installed by running pip install black. It requires Python 3.6.0+ to run but you can reformat Python 2 code with it, too.

Ref: https://black.readthedocs.io/en/stable/installation_and_usage.html

Based on this topic (https://github.com/psf/black/issues/439) Black requires python 3.6 to run.

Try pip3 install black if python3 and pip3 are installed.
