Unable to install iDEA

[sosukesumi]

Hi, I'm having trouble with installing iDEA, I'm using mac os catalina and catalina seems to cause a lot of trouble, I've tried several solutions and they don't help. The error code is attached. Do you have any solution for me?

Hi @sosukesumi,

It seems the gfortran is not well installed on your Mac based on the message " library not found for -lgfortran". Please check this link for the gfortran installation to see if it helps.

Best, Ying
