@walterdavis that’s it!

Looks like something called railties knits the desired version with the installed Gem.

rob@quark /tmp % which rails
/Users/rob/.rbenv/shims/rails

rob@quark /tmp % rails -v
Rails 8.0.0.rc1

rob@quark /tmp % gem list ^rails$

*** LOCAL GEMS ***

rails (8.0.0.rc1, 7.2.1.2, 7.1.3.2, 7.1.3)

rob@quark /tmp % rails _7.2.1.2_ -v
Rails 7.2.1.2

rob@quark /tmp % rails _7.2.1.X_ -v
/Users/rob/.rbenv/versions/3.3.0/lib/ruby/3.3.0/rubygems.rb:259:in `find_spec_for_exe': can't find gem railties (= 7.2.1.X) with executable rails (Gem::GemNotFoundException)

Thanks again
