Cannot Load Such File mail/indifferent_hash. Maybe zeitwerk?

[metaskills]

Just created a new Rails v7.0.4 app and got the latest mail v2.8.0. Seems the new version broke Rails with the following error. If I downgrade to 2.7.1, everything works fine with this new Rails app in production env.

"errorMessage": "cannot load such file -- mail/indifferent_hash",
"errorType": "Init<LoadError>",
"stackTrace": [
"/app/vendor/bundle/ruby/3.1.0/gems/zeitwerk-2.6.6/lib/zeitwerk/kernel.rb:38:in `require'",

Same issue :-]

UPDATE

chmod 644 /var/lib/gems/3.0.0/gems/mail-2.8.0/lib/mail/indifferent_hash.rb
chmod 644 /var/lib/gems/3.0.0/gems/mail-2.8.0/lib/mail/fields.rb
chmod 644 /var/lib/gems/3.0.0/gems/mail-2.8.0/lib/mail/elements.rb 

Fixed the problem.

Perhaps a gem packing issue? Here is what I see when I fetch and unpack the gem. Seems elements.rb, fields.rb, and indifferent_hash.rb lack some read perms. Could be more in some sub dirs? Maybe a repush to rubygems?

gem fetch mail
gem unpack mail-2.8.0.gem
ls ./mail-2.8.0/
ls ./mail-2.8.0/lib/mail

This seems to be related to #1489

[metaskills]

Now that 2.8.0 is released. Maybe time to fix it? How is this gem packaged and pushed to rubygems?

[benlangfeld]

This is a duplicate of #1489 . Maybe this issue should be closed to help keep the list of open issues concise and manageable for the project's maintainers :)
