$ cat Gemfile
source "https://rubygems.org"

$ cat test.rb
require "base64"

$ bundle exec ruby test.rb

$

In this situation, bundle exec ruby test.rb should print a warning: base64 which will be not part of the default gems since Ruby 3.4.0.

Note that ruby test.rb shows the warning, which is not needed (see #19885).

$ ruby test.rb
test.rb:1: warning: base64 which will be not part of the default gems since Ruby 3.4.0

Thank you for reporting this.

I confirmed it. It caused bundle exec ruby couldn't call Bundler.setup.

It's working with that.

$ cat test.rb
#!/usr/bin/env ruby

require "base64"

$ bundle exec test.rb
test.rb:3: warning: base64 will be not part of the default gems since Ruby 3.4.0. Add base64 to your Gemfile. Also contact author of  to add base64 into its gemspec.

bundle exec will call Bundler.setup only script that has ruby shebang.

I'm considering how call Bundler.setup via bundle exec ruby.
