[Tutor] Error When Using CoolProp

Wed Nov 24 15:17:15 EST 2021

Hello

I am having trouble using CoolProp with python. I have macOS Big Sur 11.5.1 with python version 3.10.

import CoolProp.CoolProp as CP
is giving me the error ModuleNotFoundError: No module named ‘CoolProp.CoolProp’ because it is not installed. I am however using it with MATLAB with no issues. I assume each software has its own wrapper?

So I tried installing CoolProp using pip install coolprop, and got the following error:

  Preparing metadata (setup.py) ... done
Using legacy 'setup.py install' for coolprop, since package 'wheel' is not installed.
