By default, binaries installed by gem will be placed into:
  /usr/local/lib/ruby/gems/2.7.0/bin

You may want to add this to your PATH.

ruby@2.7 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have ruby@2.7 first in your PATH, run:
