An error occurred while installing libxml-ruby (3.2.3), and Bundler cannot continue.

Let me know if I can help with more information.

[cramt]

had this same problem on arch, downgrading libxml2 to 2.9.14-1 fixed the problem

[cfis]

Yes looks like the same issue as #192. See comment there. Will close this ticket.
