Error when installing Constituent Tree Lib in Python

Question

I am trying to use the so visually attractive Constituent Tree Lib in Python : https://github.com/Halvani/Constituent-Treelib. I have followed the steps in the installation (pip install, ...), but I get this error :

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

Does anyone know about how to fix the problem? Thanks so much in advance.
