sq_mini_racer Ruby 3.1 incompatibility (`Psych::DisallowedClass`)

[64kramsystem]

Hello!

It seems that sq_mini_racer is incompatible with Ruby 3.1 (works on Ruby 2.7/3.0).

When I try to install it, I get this stack trace:

Psych is v4.0.3. I'm on an Ubuntu 22.04 system.

Hey @64kramsystem 👋

sq_mini_racer is a fork (see over here https://github.com/sqreen/mini_racer). Any reason you're not using mini_racer directly?

Hi there!

Oh, sorry for that, I didn't know it :flushed:

It's a dependency of a gem I've used (sqreen). I'm closing the issue, and will open it in the related repository/ies :smile:

Thanks! :smile:
