Bundler compatibility with Ruby

The latest Bundler release should always support, at the very least, all rubies that have not yet reached their End of Life date.

Bundler 2
  • Requires a minimum Ruby version of 2.3.0.
Bundler 1
  • Requires a minimum Ruby version of 1.8.7.

Bundler compatibility with RubyGems

The latest Bundler release should always support all RubyGems versions higher than or equal to the one shipped with the oldest Ruby version supported. RubyGems is not allowed to be downgraded further than that, so upgrading or downgrading RubyGems should not affect Bundler.

Bundler 2
  • Requires a minimum RubyGems version of 2.5, since that's the version of RubyGems included with Ruby 2.3.0.
Bundler 1
  • Requires a minimum RubyGems version of 1.3.6.
