Thank you so much for your help! I installed Homebrew and executed the code that you wrote out. However, when I ran the make -s V = 0 line, it still crashed in the same place. For some reason, it is unable to build the Scipy-1.6.3 package. I attached a screenshot of the error message to this email. Do you know what I'm doing incorrectly?
