Hi,

You have several options:

• Only create .exe for versions until 2.1.0 (before 2.7 support removal)
• For now, ignore Ruby requirement
  • Indeed, Ruby 2.7 support was removed for several reasons: because it's EOL, because it made the CI fails.
  • But Ruby 2.7 should still work, for now, since I did not introduce breakings changes (for examples while linting with newer syntaxes).
  • For example, gem install --force ignores dependency checks. Another option is to create a patch to change the version required in the gemspec.
  • For now, forcing the use of Ruby 2.7 should have no impact, but I can't guarantee that in the future. For now, it should work, it's just that's no longer tested against ruby 2.7 and that I won't provide help for people using this version.
• Ruby 3.0-3.3 are available on Windows via RubyInstaller so you could install haiti with gem install haiti-hash on windows too without making a .exe..
• Use another executable packager other than the unmaintained ruby-packer
  • tebako supports Ruby 3.1 & 3.2
  • ocran should work with 3.x rubies too
