TIL RVM and I are on different assumptions. I'm talking about RVM allowing unbound variables in its scripts.
I don't because I literally have run "rm -rf /" on my Mac because of an unbound variable in the past. So, when I write a shell script, the second line is always "set -eu."
And because RVM allows unbound variables, this line crashes RVM.
Then for some stupidity on my part, I looked into GitHub for its codebase first to get even more clueless about the issue before finally googling to see if anyone had experienced the same problem 🤦
