Attempt to install bundler fails
I have a CI system that runs Ruby tests via bazel inside a docker image, with a dedicated image per bazel version + ruby version that we support.
The docker image is built with the desired bazel version, and ruby is installed via RVM at docker image build time along with the version of bundler we use to generate our Gemfile.lock.
The following error is observed in the PR where I'm attempting to adopt rules_ruby, which indicates that rules_ruby is trying to install bundler-2.4.22 despite it being installed already. It fails, presumably because of bazel sandbox rules.
Is there something I need to do differently to prevent rules_ruby from attempting the installation? Does gem installation ever work when using the system version and if not, should disabling automatic installation of bundler be disabled in this configuration?

Bundler gem installation works under system toolchain, we constantly test this on CI - https://github.com/bazel-contrib/rules_ruby/actions/runs/13546882895/job/37864964054#step:6:62. I am not sure what exactly is happening in your builds, but given the Bundler is already installed in this version, we might want to skip its installation altogether. Can you try disabling it and seeing if bundle install would be passing?
To disable, you could comment out the following piece: https://github.com/bazel-contrib/rules_ruby/blob/d7cd5d675f42e59a9a9706d00e6896fc918c7eba/ruby/private/bundle_fetch.bzl#L170-L180
Patching rules_ruby to disable the installation of bundler does seem to have a positive impact.
Instead of the stack trace seen in the description, I need now see:

That's good. Unfortunately, I cannot change bundle_fetch to query Bundler version because the Ruby toolchain is not installed at this stage. I'll see if there is any way to work this around (maybe use --conservative flag in gem install).
Do you need a Docker file with a similar setup for use in troubleshooting / regression testing?
I tried to reproduce the issue locally by grabbing the protobuf repository from main, removing the patch you've added (:Disable_bundle_install.patch) and running some tests in //ruby, but everything looks fine. Please share the Dockerfile or image I could use. If it's impossible, I'll figure out how to skip bundler installation but won't be able to verify the fix.
