Issue #20060 has been updated by hsbt (Hiroshi SHIBATA). I'm not sure why this issue was fixed with `ruby 3.3.0dev (2023-12-13T07:28:22Z master 75f4a687ed) [arm64-darwin23]`. This may be affected with recent RubyGems or Bundler changes. ---------------------------------------- Bug #20060: bundled_gems.rb is not working with Bootsnap https://bugs.ruby-lang.org/issues/20060#change-105659 * Author: hsbt (Hiroshi SHIBATA) * Status: Assigned * Priority: Normal * Assignee: hsbt (Hiroshi SHIBATA) * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Addressed from https://github.com/ruby/ruby/pull/9163#issuecomment-1850924893 `bundled_gems.rb` of 3.3.0-rc1 couldn't handle full paths by Bootsnap. ``` $ rails new example (snip) rails importmap:install bin/rails aborted! ArgumentError: comparison of String with nil failed (ArgumentError) msg = " #{RUBY_VERSION < SINCE[gem] ? "will no longer be" : "is not"} part of the default gems since Ruby #{SINCE[gem]}." (snip) ``` It's working with DISABLE_BOOTSNAP=1. But we should resolve it with under the bootsnap. -- https://bugs.ruby-lang.org/
