[Ifeffit] demeter on Mac 10.14.3 Mojave

Hello, I have a new mac laptop with Mac 10.14.3 Mojave and would like to install demeter in it. Following the steps in the website, everything worked ok during the installation. However, when I finally typed “athena” in the terminal, the following warning showed up. If I clicked OK, the Athena will just quit and gave a message “perl5.26 quit unexpectedly”. The same thing for Artemis. Hephaestus showed the same warning, but still works after clicking OK. Any clue to fix this problem? [cid:image001.png@01D4DDCA.F5FB5AD0] Thanks a lot! Yuan
