For several weeks, we’ve been getting error messages like this when we try to use any
brew commands inside of our macOS build:
Homebrew must be run under Ruby 2.6! You’re running 2.3.3
Example build: https://travis-ci.org/terralang/terra/jobs/624807937
This seems to make it impossible to actually use Homebrew from inside of Travis. Is there a workaround or can this be fixed?
