(Arch Linux) Ruby missing 'erb'

[DVD-DAVIDE]

On Arch Linux, the default ruby package does not, for some reason, contain the erb class (or module/whatever it is called in ruby).
It is instead in the separate package ruby-erb.

I believe the Arch install guide in the wiki should at least mention this, in order to avoid any issues one might have (as I did).

This was also mentioned here: rbenv/ruby-build#2518

Sup does not use ERB directly. Although maybe some of its dependencies do.

Can you paste the exact command you were running (gem install sup, or something else? running an installed sup command?) and paste the error it produced (with any stack trace) when you ran it on Arch without the ruby-erb package installed?

I am just trying to understand where exactly the issue is, to decide on the best fix.

I understand what you mean.
It seems like the request is from kernel_require.rb.

On my machine, the related packages available are ruby 3.4.7-1 and rubygems 3.6.9-1 (from Omarchy's mirror, if that's relevant). I installed sup with gem install sup, and it's up to date (v1.3).

I can recreate this by simply running sup:
