The Error that I dont know

Hi community! I have trouble with the error shown in the screenshot. What should I do?
Please show the way to solve step by step.

This is indicating the needed environment variables for the physics data libraries have not been set. Please see the Postinstall Setup section of the Installation Guide for the steps needed to set these up.
