Bug #18789
Updated by Peter Amstutz almost 3 years ago
# ruby 2.6 and onward has bundler as part of the standard library. This means Ruby 2.5 and 2.6+ behave differently.
# When you run bin/rails and it does @require 'bundler/setup'@ it uses Ruby's built-in bundler.
# Ruby's built in bundler finds the "BUNDLED WITH" line and adds a dependency on bundler 2.2.19
# It tries to find "bundler 2.2.19" gem
# It can't find it. I don't know why because it's installed.
