Can't install webwork on MacOS

[cmd16]

Running Mac OS Sierra 10.12.6.
I know there used to be a script to download webwork on MacOS, but the website says it is be deprecated. I tried this script, but It's not working. Here is the terminal output. I can't find webwork anywhere.

Working in /var/folders/zn/tr7_57591919694q_1vmv5pr0000gp/T/
## Installing cpan, and friends just to be sure.
## Download the latest webwork installer
