Subject: [ruby-core:115603] [Ruby master Bug#19886] "default->bundled gem" warning is not shown under "bundle exec"

Issue #19886 has been updated by hsbt (Hiroshi SHIBATA).

Status changed from Assigned to Closed

I investigate this again.

`bundle exec ruby` called `Bundler.setup`. But `Gem::BUNDLED_GEMS` is not loaded because `bundle exec ruby` ignore to load `gem_prelude.rb`. I'm not sure why `bundle exec t.rb` is load `gem_prelude.rb` yet.

This is fixed by https://github.com/rubygems/rubygems/pull/7224.

```
$ 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
```
