Stop using deprecated argument to `gem` (!24079) · Merge requests · GitLab.org / GitLab FOSS · GitLab

Sean McGivern requested to merge fix-prepare-build-script into master Dec 31, 2018

--no-rdoc and --no-ri have been deprecated since RubyGems 2.0: https://github.com/rubygems/rubygems/blob/v2.0.0/History.txt#L43

They were finally removed in a recent release: https://github.com/rubygems/rubygems/pull/2354

Related to https://gitlab.com/gitlab-org/gitlab-ce/issues/55740 (doesn't close it; that issue is about documentation).
