'pip install fails with heatmap

I'm trying to install heatmap with pip but this error comes out and I don't know how to solve it.

This is the error that cmd shows to me.

$ pip3 install heatmap
Collecting heatmap
  Using cached heatmap-2.2.1.zip (25 kB)
  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error

  note: This error originates from a subprocess, and is likely not a problem with pip.

Version:

pip: pip 22.0.4

python: Python 3.9.7

That's a syntax error indicative of Python 2 syntax in Python 3.

The heatmap project is compatible with Python 2 only, quoth their website:

Requires Python 2.5+.

That latest version is from 2013, anyway. You'll need to find a more modern, or at least maintained, version to work with Python 3.
